The purpose of this study is to reduce production time and to minimize the risk of design failure. In this study using the Catia software to design a rim, then simulate the effect of applying force on a component, applying a certain working pressure, then able to perform calculations and display the results for analysis. The analytical method used is the FEM method of static analysis. The mesh type uses a linear tetrahedron mesh. Provision of clamps or fixed constraints is carried out on the surface of the bolt hole, where this surface is in contact with the wheel holder of car drive system. Then given a circumferential loading of 200 kN/m2. It was found that aluminum material is the best for the manufacture of car rims, which has a low density so it is lighter than steel and titanium. However, alloys such as lead and magnesium are needed to increase their hardness, and chromium alloys are needed to protect the rims from corrosion due to use in a polluted environment and contain impurities that can trigger corrosion.","PeriodicalId":32811,"journal":{"name":"JEMMME Journal of Energy Mechanical Material and Manufacturing Engineering","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78123234","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To show the change in the toughness of the polyester material, a test is carried out to provide a tensile load and a flexural load until the material breaks This work reports the successful fabrication of polyester blends by mixing vinyl esters with different percentages. The test shows that there is a linear relationship between the shape of the fracture surface due to bending loads and observations through SEM which are directly related to the flexural stress properties with the fracture surface morphology. The mixture of polyester with 40% vinyl ester showed the highest flexural stress of 126.88 MPa while for pure polyester of 49.71 MPa this showed an increase of 255.24% compared to pure polyester. This shows that the addition of vinyl ester to polyester resulted in an increase in the toughness of the polyester, but for 100% vinyl ester the return stress decreased by 56.50 MPa. This indicates that due to the breaking of some of the polyester chain networks causes a decrease in the structural stiffness, which results in an increase in the plastic deformation zone fraction.

This study aims to determine the effect of pack carburizing treatment on the microstructure and hardness of AISI 1010 steel. The material was then cooled slowly in the oven to a temperatur of 150oC which was then followed by air cooling. Single Quenching is then carried out by reheating the carburizing material to a temperature of 870oC and then holding it at that temperature for 60 minutes. Quenching is done by cooling the material quickly using a cooling medium of varying viscosity. The results of the composition test showed an increase in carbon content to 4.1159%. The results of microstructure observations showed that a massive pearlite structure was formed to a depth of ± 0.794 mm on the surface of the carburizing specimen. The results of the hardness test using the Vickers method showed that the hardness value of the raw material increased after carburizing to 217.88±5.13 HV due to the formation of a pearlite structure. With this increase in hardness, the application of AISI 1010 Steel material becomes wider. \u0000Keywords: Carburizing, Quenching, Viscosity, Hardness, Microstructure","PeriodicalId":32811,"journal":{"name":"JEMMME Journal of Energy Mechanical Material and Manufacturing Engineering","volume":"6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-11-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87381130","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For forward kinematics solution, two cases are presented. The first case is that one MLFFNN is designed and trained to find only the position of the robot end-effector. In the second case, another MLFFNN is designed and trained to find both the position and the orientation of the robot end-effector. Both MLFFNNs are designed considering the joints’ positions as the inputs. For inverse kinematics solution, a MLFFNN is designed and trained to find the joints’ positions considering the position and the orientation of the robot end-effector as the inputs. For training any of the proposed MLFFNNs, data are generated in MATLAB using two different cases. The first case is considering incremental motion of the robot joints, whereas the second case is considering a sinusoidal motion. This method is designed to be generalized to any DOF manipulator. For simplicity, it is applied using a 2-DOF planar robot. The results show that the approximation error between the desired and estimated output is very low and approximately zero. The MLFFNN is efficient to solve the forward and inverse kinematics problems.
