Wheel rims are one of the important parts of automotive, where it is heavily undergoes static and fatigue failures as the wheel travels in different road conditions. As it develops, the heavy stress produced, critical stress and number of cycles to failure were found. The design and shape of the wheel rim were to be accommodated for the requirement of vehicle. The wheel rims are mostly employed alloy materials with suitable parameters. A 3D model of wheel rim was made with Creo Parametric Software and then it was converted into IGES format and imported into ANSYS. Static analysis was performed using ANSYS 19.2 software and results were obtained by performing the analysis, it gives the differences in the behaviour of the model. In this static analysis, we found out Equivalent Von-mises stress, Equivalent Elastic strain and Total Deformation by applying fixed supports in lug holes and pressure of 0.27579 Mpa (40 psi) is applied on the outer surface of the rim for 3 different materials such as Steel, Aluminum alloy and Magnesium alloy.

Flexible tubes are commonly used in automobile and piping systems to absorb expansion and contraction in order to reduce stress. Unlike to other piping components, flexible tubes consist of a thin walled shell of revolution with a corrugated meridian, in order to provide the flexibility needed to absorb mechanical movements. It is very complicated to analyze the behavior of flexible tubes because of its complex figure. Some fundamental behavior of the flexible tube for automobile is reported with analysis method. Obtained results are as follows; (1) The von-Mises stress is increased with increase of deflection at the flexible tube end and the linearity of stress variation depends on length of the flexible tube. (2) The number of cycles to failure is decreased with increase of deflection at the flexible tube end.

Digging Efficiency

Within the scope of this paper, various bucket tooth designs and a biomimetic bucket design were created in order to produce a solution on digging efficiency which is one of the general problems of construction machines. These designs were inspired by giant anteater and American badger front claws. The inspiration aspect was diversified by integrating the paw and claw curves of the giant anteater and by bringing American badger claws into the design in different ways. Furhermore, the designed biomimetic bucket alternatives were compared between each other and the standard bucket equipment used in the market by making a computer aided static analysis. The compared criteria were the equivalent stress and total deformation formed on the bucket itself, the excavation equipment and the excavated soil. According to the analysis results, when the bucket tooth named P2 is mounted to the standard bucket, it has 42% lower Von-Mises stress on than standard bucket tooth. Additionally, it is exposed 4,7% less total deformation than standard tooth. Also, in terms of maximum Von-Mises stress formed on the soil model, P2 causes 17,5% greater stress than the standard bucket tooth.

Orofacial injuries are common occurrences during contact sports activities; however, there is an absence of data regarding the performance of hybrid occlusal splint mouthguards, especially during compressive loading. To evaluate the total deformation and stress concentration, a skull model was selected and duplicated to receive two different designs of mouthguard devices: one model received a conventional custom-made mouthguard (MG) with 4-mm thickness and the other received a novel hybrid occlusal splint-mouthguard (HMG) with the same thickness. Both models were subdivided into finite elements. The frictionless contacts were used, and a nonlinear analysis was performed simulating the compressive loading in occlusion. The results were presented in von-Mises stress maps (MPa) and Total Deformation (mm). A higher stress concentration in teeth was observed for the model with the conventional MG, while the HMG design displayed a promising mechanical response with lower stress magnitude. The HMG de-sign displayed a higher magnitude of stress on its occlusal portion than the MG design. The hybrid mouthguard (HMG) reduced (1) jaw displacement during chewing and (2) the generated stresses in maxil-lary and mandibular teeth.

The inflatable bedpan is designed to provide comfortable, convenient, safe, hygienic, efficient and easy to use to the patients and their caretakers. In order to investigate the suitability thickness of inflatable bedpan for the pressure inflow in bedpan tube, the analysis is done using Catia analysis. The static analysis work is carried out to inflatable bedpan cross section of polyvinyl chloride (PVC) and their relative performances have been observed respectively. The thickness 0.5 mm shows the highest Von Mises Stress which is 21100 kPa compared to 0.8and 1.0 mm thicknesses. The lowest Von Mises Stress observed at thickness 1.0 mm which is 2990 kPa. The less stress obtained can encourage perfect shape of the design. In this paper, by observing the result of static structure analysis obtained, 1 mm is suggested as best thickness to be used as an inflatable bedpan wall because it can withstand more pressure while maintaining its stability.

The present study aims to investigate crack presence in a rigid steel beam so that it can be considered in structural design. A finite element method (FEM) had been used with the Ansys 16.1 software to simulate the whole steel body with three different forces and moments with a magnitude force subjected at the free end of the beam. The steel rod had been considered as simple cantilever to be modelled by the software. Von Mises stress had been considered in the simulation process where the maximum value of stress due to applied load and moment was 1.9 MPa. Total deformation of the whole body had also been considered to instigate the maximum deformation (4.3mm) due to applied loads and moments. Furthermore, MATLAB and through fuzzy logic had been used to assist in the investigation of cracks. Both approaches had been governed by the Euler-Bernoulli theory for free vibration of motion equations. The other aim of this study is to evaluate results received from the Ansys with MATLAB for the same boundary conditions as the case.

<p><em>The PPCW railroad flatcars is railroad flatcars used to transport container loads with a maximum load capacity of up to 42 tons. In its use, these railroad flatcars are used to transport the cement bags in the pallet arrangement resulting in crack in the bottom frame of the PPCW railroad flatcars structure. The purpose of this analysis is to find out stress value and deformation value that occurred in the railroad flatcars due to the cement bags loading. The analysis process begins with modeling according to the original size of the railroad flatcars which is then followed by providing the support, gravity, loads, and material specifications used. Based on the result of analysis that has been obtained from the load of cement bags of 546,000 N and ratchet lashing of 900,000 N on the frame of PPCW railroad flatcars, we obtained the maximum von Mises stress value of 231.91 MPa arising on the bottom frame of the PPCW railroad flatcars structure as the site of cracking and the maximum total deformation value of 19.526 mm arising in the center of the railroad flatcars. The PPCW railroad flatcars made from SS400 with yield strength value of 245 MPa. Therefore, it was found that the value of stress arising in the railroad flatcars is still in the safe area and is allowed</em><em>.</em><em></em></p>

For cutting down the stress and displacement of banded wedge and synchronous V belt drive in the transmission process, promoting the transmission mechanism, and improving quality of the belt drive, the working principle of the transmission mechanism was introduced briefly. The three dimensional solid model of the transmission mechanism constituted in pro/e; the main parameters of the model were set using ANSYS Workbench. And then the serialization simulation analysis of the transmission mechanism was achieved when the tension force is located in the point of the V belt entering meshing with the driven wheel; the cloud diagram of Von Mises stress and the maximal Von Mises stress and total deformation of the transmission mechanism were elicited. The simulation results were analyzed. The simulation results show that maximal total deformation has a minimum value with increasing the tensioning force. Reducing becomingly the tensioning force in ensuring natural belt drive the maximal Von Mises stress reduces effectively. Augmenting the active force the maximal equivalent stress rarely reduces and the maximal total deformation remains unchanged. Adjusting opportunely the location of the tensioning force the total deformation reduces effectively and the maximum equivalent stress changes smaller.

Deep soil loosening machine MAS 65 is destined to work soil at depths exceeding 45 cm, thus the machine’s frame is subjected to loads which could affect its structural integrity. Within this paper a static structural analysis was performed on the machine’s 3D model using finite element method and strain and stress distribution maps were created. Using the Von Mises stress map there were identified several critical points which could fail during normal exploitation conditions and which should be monitored by strain gages during field tests in order to prevent structural failure.
