This paper describes a new drum-type fruit-vegetable washer, which is created on the basis of manual vegetable washing method. The main driving part of the washer is a crank mechanism with springs. The main drive design process is proposed to be carried out in two stages: dynamic research and strength analysis. The results of dynamic research show the effect of spring stiffness on reducing dynamic reactions in the crank mechanism as well as the required engine power, in other words, on reducing washer vibration and energy consumption. Stress analysis was performed using the finite element software package ABAQUS. The design process allows selecting a set of acceptable parameters for the main drive of the washer. This result is used to create a prototype of an innovative fruit-vegetable washer.

PurposeThe purpose of this paper is to present the design and development of transfer seat system which aids the disabled drivers to get in and out of the car without outside help thereby reducing physical effort. The design of the model is carried out taking into account the vehicle specification and the weight of the person. After careful measurement and analysis, the required seat system parameters were estimated. The three movements associated with the system are satisfied with motors controlled by switches. The design calculations and the tests carried out are validated using the ANSYS finite element software.Design/methodology/approachThe whole process begins with the definition of the problem of eliminating the support of an additional person to help people with disabilities enter and leave a car, making it feasible and economical for the patients. Literature review includes and develops information from different sources. The research gap is identified and a necessary improvement is proposed. Design and analysis involves optimum design and calculation that achieves the efficiency, reliability and comfortable movement of the system. It also involves validation to support stress analysis in the system that is performed using ANSYS. The material supply includes the required materials taking into account factors such as strength, durability and availability. Manufacturing selects appropriate manufacturing techniques taking into account design, materials and space limitation. Operations such as welding, cutting, drilling and grinding are considered. The tests consist of performing a physical test to check the approximate load capacity of the system for a gentle, comfortable and secure comfort. Validation ensures that the results of the test coincide with the existing results of the supporting documentation. This process also involves taking corrective action and re-doing the design process to achieve the desired results.FindingsThe results that are plotted suggest that with the increase in downward force, the power required to balance it is greater. Similarly, the speed increases with increasing power. ANSYS analysis can be performed for the support structure and for obtaining deformation. The entire work can be implemented on the actual vehicle, and the time required for the patient to enter and exit could be calculated. The entire transfer system that operates by the engine can be modified, and a hydraulic system can be used to make the movements possible. The section of the rail can also be modified accordingly, and the comparison of the possible results can be carried out with the present system.Research limitations/implicationsThe entire system can be improvised by working on the mechanism which reduces the overall operating time without causing discomfort to the user when entering and exiting the car. Furthermore, the safety feature must be considered in the car to prevent the mechanism from altering the seating position of the seat, for which a mooring system can be inserted with a switch to hold it in place and release it. A powerful motor can be integrated into the mechanism to improvise the second movement, which is the deployment of the legs on the ground with the motorized wheels. The set of cast iron rails is used to support more weight without failure.Practical implicationsThe main objective is to design a system that allows a disabled person to enter and exit easily without the support or assistance of a second person. The design process had to be modified, and various methods were tried to incorporate this flawless movement onto the chassis of the car. Necessary changes have been made in the case of the material used and of the yarn to obtain the desired movement at the desired speed at the desired time. By performing these three movements, the secondary objective had to be integrated into the system to automate the door to facilitate the entry and exit of the car and to open the door simply by pressing a button. These results were taken into account to make the engine speed changes and the speed at which the chair will descend and move horizontally to ensure a safe design.Social implicationsThe developed transfer seat system can be widely used in healthcare sectors which greatly helps the movement of disabled persons.Originality/valueThe design calculations and tests carried out are validated using the ANSYS®, a finite element software.

AbstractThis paper presents the design process for an innovative latch mechanism in a standard mechanical interfaced (SMIFed) wafer container, in which the manufactured integrated circuits are stored. An innovative latch mechanism is proposed and applied to the wafer container, such that the container door can be latched and air-tightly sealed during storage or transportation. The design process is divided into two stages. In the first stage, an output slot-cam is designed in order to generate decoupled fine motions of the output link. The issue is formulated as an optimization problem where the output link dimensions are optimized to minimize the resultant pin forces subject to an adequate transmission angle. In the second stage, the input slot-cam is designed to achieve that kinetic energy of the elastic gasket on the container lid is absorbed at a uniform rate. Finally, a numerical example and computer simulations are given to demonstrate the results of design process. It is believed that this work could aid in enhancing the performance and reliability of the latch mechanism in the SMIF environment.

Solar energy, as a major source of clean energy, has gradually been applied in ship industry, but it has rarely been used in large transport vessels. This paper takes VLCC (Very Large Crude Carrier) as the study object and presents a design scheme of PV (photovoltaic) modules and their supports on the deck of an oil carrier. In accordance with current ship norms and standards, the rocking inertia force and wind pressures acting on both the PV modules and the supports at different wind velocities are computed using the finite element software of Ansys and Fluent, and the simulated wind pressures are compared to the formula-based calculation results. Stress and displacement of the supporting leg in marine environment are calculated and the supports is structurally optimized as well. In the end, a simulation method for checking the strength of the solar-powered oil carrier is presented, and the scheme of adding a knee plate to decrease stress concentration at the intersection of the three tubes of the leg is proposed.

The article presents the design process of the gerotor pump body made of plastic. As the shape of the projected body a simple prism with a square base was adopted. That body shape is called the basic. It consists of three parts: front, middle and back body, which are connected by a screw joint. This shape was subject to strength analysis, using the FEM method. As a result of these analysis, the place and nature of the stress and deformation of the basic body shape was determined. It was established that the body is deformed in both axial ie. along the pump shaft axis, and radial directions, ie. perpendicular to the axis of the shaft. There have been made modifications to the basic shape of the body in order to reduce the stress and deformation. As a result of these modifications, the modified body shape was obtained, which was then subjected to strength analysis by FEM method. It was found that the modifications resulted in reduction of the stress and deformation. Reducing the stress values, enables loading of pump body with higher operating pressures. Reducing the deformation of the body leads to a reduction in axial and radial clearances in the pump and enables achieving higher efficiency.

Abstract Most of the front loaders are compact structures that do not allow loading at greater heights. On the Polish and foreign market, there was a need to develop a front loader design that would allow to increase the loading height. As a result, the front loader was designed a front loader with the possibility of extending the arms for the Kubota M5 agricultural tractor. The system enables unloading and loading of cubes, straw and hay bales on higher piles. Before starting the design process, the available front loader solutions were analyzed and on this basis, three concepts of design solutions were proposed. These concepts were scored on the basis of the adopted criteria and the one with the highest number of points was selected. For the selected concept, strength analytical calculations and verification calculations using the FEM method were performed. The developed loader is innovative compared to other available designs and has a good chance of implementation.

Different approaches are usually taken when designing flexible and rigid pavement: the rigid concrete slab carries major portion of the traffic load; while for flexible pavement, external loads are distributed to the subgrade because of the relatively low modulus of elasticity of asphalt layer comparing to concrete in the case of rigid pavement. Pavement engineering has gone through major developments; the transition from Empirical Design Method to Mechanistic-Empirical Methods is becoming a near-future trend. The Mechanistic-Empirical Method has two components: (1) stress, strain and deflection are calculated based on analyzing mechanical characteristics of materials; (2) critical pavement distresses are quantitatively predicted by experimental calibrated equations. Hence, stress analysis has become an important role in pavement engineering. The most practical and widely used stress analysis method for flexible pavement is Burmister's Elastic Layered Theory; and for analyzing rigid pavement is Finite Element Method. KENSLABS and STAAD-III are both Finite Element software; KENSLABS is designed specifically for concrete pavement stress analysis, therefore it is more user-frielndly for pavement design; STAAD-III is more suitable for general plane and space structures. The project compares the use of both software for stress analysis in rigid pavement in term of simplicity and precision.

Global Strength

Offshore structure global strength analysis based on finite element plate model is a requirement for today’s classification societies and designers. Wave, wind, current loads have to be applied to the global strength model as a pre processing step to allow the analysis to take place. After the analysis, code checking must be performed to verify if the structure meets class or other requirements. Due to its complex nature, a large amount of engineering hours have to be spent for the pre and post processing. This is not only lengthy if performed manually or semi-automatically, but also mistake prone. General guidelines from classification societies exist, but general purpose commercial software is scarce and often still requires significant amount of engineering time to perform these tasks. This paper shows a rational approach to automate the pre and post processing of offshore structure global strength finite element analysis. Utilizing the FEMAP Application Program Interface (API), a complete automatic pre and post processing is implemented in one integrated program, Exmar Design Suite (EDS). The program will load the model from WAMIT generated wave pressure, apply internal pressure induced from motions to internal tanks, and also apply other environmental loads. After the finite element analysis, the program can execute strength code checking including yielding and buckling for the model. Both beam and stiffened plate panels can be identified using an automatic search algorithm, which is not a function available for general finite element software. The panels and beams are then checked against various common codes such as API/AISC/ABS/DNV. In addition, fatigue analysis can also be performed in either spectral or simplified approach. The benefits of automation are timesaving, accuracy and reliability. It also makes the check of whole model possible. Instead of relying more on “screening” or experience based structure check, engineers will have more confidence in the results by going through the whole model.
