This article presents architecture of integrated intelligent computer-aided design system for designing mechanical power-transmitting mechanisms (IICADkmps). The system has been developed in C# program environment with the aim of automatising the design process. This article presents a modern, automated approach to design. Developed kmps modules for calculation of geometrical and design characteristics of mechanical power-transmitting mechanisms are described. Three-dimensional geometrical parameter modelling of mechanical power-transmitting mechanisms was performed in the computer-aided design/computer-aided manufacturing/computer-aided engineering system CATIA V5. The connection between kmps calculation modules and CATIA V5 modelling system was established through initial three-dimensional models – templates. The outputs from the developed IICADkmps system generated final three-dimensional virtual models of mechanical power-transmitting mechanisms. Testing of the developed IICADkmps system was performed on friction, belt, cogged (spur and bevel gears) and chain transmitting mechanisms. Also, connection of the developed IICADkmps system with a device for rapid prototyping and computer numerical control machines was made for the purpose of additional testing and verification of practical use. Physical prototypes of designed characteristic elements of mechanical power-transmitting mechanisms were manufactured. The selected test three-dimensional virtual prototypes, obtained as an output from the developed IICADkmps system, were manufactured on the device for rapid prototyping (three-dimensional colour printer Spectrum Z510) and computer numerical control machines. Finally, at the end of the article, conclusions and suggested possible directions of further research, based on theoretical and practical research results, are presented.

Control moment gyroscope or two-axis balking gyroscope is used in spacecraft orientation systems. The control moment gyroscope is a complex electromechanical system with different parameters which connect by means of specific instant and inverse dependences. This fact could complicate the design process as of getting the optimal parameters the search of construction variations becomes harder. To simplify the control moment gyroscope designing process and increase its efficiency the computer-aided design system could be as highly useful. The computer-aided design system which is used in the present research and described in the article consists of five main subsystems. They cover the main stages of control moment gyroscope designing.

A VLCC (very large crude oil carrier) has approximately 1000 curved longitudinal beams, many of which have three-dimensional complicated curvatures. Due to the shortage of highly skilled workers and the need to keep costs down, production and structural designers have worked to reduce the number of such beams. In order to meet the requirements of production, the authors' company has attempted several design approaches for the longitudinal beam layout to reduce the number of beams that have complicated curvature. Recently, through the application of a computer-aided design system, which has been improved for shipbuilding based on the Calma's system, a new design method for the longitudinal beam layout has been successfully developed. A significant number of beams with a twisted configuration have been eliminated and replaced with beams of simpler, two-dimensional shapes. This paper shows the transition of these design approaches, and the application of the new design to building a VLCC.

Currently, the reforestation process has a number of disadvantages, such as the need to use manual labor during the distribution and planting of seedlings; mechanisms for planting seedlings are often equipped with tractors as traction means. The creation of furrows and the preparation of the soil immediately before planting affects the energy consumption of the implements’ drives. At the moment, the inefficiency of planting work is high, since the planting of seedlings with a closed root system occurs in conjunction with a plow. All these factors, when calculated for a long-term period, lead to greater energy consumption when carrying out this type of work. This article discusses approaches to the mechanization of the planting process. Using the experience of planting seedlings with a closed root system (CCS) manually and analyzing the methods of mechanization of planting, it is possible to obtain maximum efficiency when carrying out this type of work. Based on the material studied, a prototype of a planting device suitable for the technology of discrete planting of seedlings with ZKS was selected. Solid modeling of the working body in the Solidworks computer-aided design system has been carried out. When designing the model, the possibility of its production using additive technology using the FDM printing method was envisaged.

The Impact

Today, product design process is facing a market globalisation led by distributed teams. The international market context, in which industrial companies evolve, leads design teams to work in a large multidisciplinary collaborative context using collaborative practices. In this context, product design process is driven by the integration and optimisation of stakeholders’ collaboration. Thus, to facilitate collaborative steps, new management strategies are defined and new information systems can be used. To this end, we have focused our article on the topic of collaborative product design project management. We have underlined the necessity to use quantitative and non-intrusive indicators during the management of collaborative design phases besides subjective evaluations. Tracking these indicators is performed in parallel to the existing approaches in order to evaluate the performance of collaborative design project. Moreover, these indicators can show the impact of the collaboration steps on the design project evolution. The computation of proposed indicators is based on precise metrics which details the completeness of the computer-aided design model and its evolution depending on the used collaborative tools and the project milestones. This computation uses the importance of each computer-aided design model part and the transformation rate of each part of the computer-aided design model.

Solar roofing panels fulfill both building protective functions and energy generating ones. The composition of the substrate of the solar roofing panel includes secondary raw materials, which has a positive effect on the environment. To increase the electrical efficiency and also to obtain thermal energy in the form of warm water, it was proposed to create a photovoltaic thermal roofing panel. For this purpose, the presented article describes the method of creating a three-dimensional model of solar photovoltaic thermal modules in a computer-aided design system. The article also proposes a method for manufacturing a prototype body for a solar roofing panel, manufactured using additive technologies, which will significantly reduce costs at the initial stage of creating a prototype due to the possibility of operational changes to a three-dimensional model followed by printing a modified and optimized model. To reduce the number of photovoltaic cells and the cost of a solar roofing panel, it is proposed to use a solar concentrator in the panel.

Purpose The purpose of this paper is to establish new computer-aided-design (CAD) framework to design custom product that is fabricated additive manufacturing (AM), which can produce complex three-dimensional (3D) object without additional tool or fixture. Additive manufacturing (AM) enables the fabrication of three-dimensional (3D) objects with complex shapes without additional tools and refixturing. However, it is difficult for user to use traditional computer-aided design tools to design custom products. Design/methodology/approach In this paper, the authors presented a design system to help user design custom 3D printable products based on some reference freeform shapes. The user can define and edit styling curves on the reference model using the interactive geometric operations for styling curve. Incorporating with the reference models, these curves can be converted into 3D printable models through the fabrication interface. Findings The authors tested their system with four design applications including a hollow patterned bicycle helmet, a T-rex with skin frame structure, a face mask with Voronoi patterns and an AM-specific night dress with hollow patterns. Originality/value The executable prototype of the presented design framework used in the customization process is publicly available.

Compression Mold

Compression mold processing of composites involves taking the charge through a material dependent temperature and pressure path, inducing thermochemical reactions to cure the charge. While curing, specific uniform temperatures are required for a time, and spatial variation of the cavity surface temperature can lengthen time needed to cure and also cause voids and residual stresses, reducing the quality of the finished part. Towards mold heating design goal of uniform cavity surface temperature, an interactive CAD system for compression mold heating design has been developed. The system accepts a previously defined three dimensional, discretized goemetry and uses a Boundary Element Method (BEM) analysis which includes the effects of long, thin electric resistor heating rods, and is coupled with the CONMIN algorithm for constrained minimization of an objective error function to obtain uniform temperature over the cavity surface. Realistic constraints are featured to insure design feasibility. The problem is organized with design in mind to allow fast, easy redesign and a sensitivity study along with the optimization. The approach used is unique and is the first application of this type of optimization to three dimensional mold heating design. An example of the whole design process including creation, reviewing, optimization, and redesign of curved mold example is presented for results.
