Static structural CAE analysis of symmetrical 65Si7 leaf springs in automotive vehicles

Using CAE tools, ideal type of contact and meshing elements have been proposed to achieve results closer to the experimental results. The analytical method for static analysis of the leaf springs has also been described. CAE results have been compared with experimental and analytical results for validation. | Nội dung Text Static structural CAE analysis of symmetrical 65Si7 leaf springs in automotive vehicles Engineering Solid Mechanics 3 2015 59-74 Contents lists available at GrowingScience Engineering Solid Mechanics homepage www.GrowingScience.com esm Static structural CAE analysis of symmetrical 65Si7 leaf springs in automotive vehicles Vinkel Kumar Aroraa Gian Bhushanb and M.L Aggarwalc a Department of Mechanical Engineering ITM University Sector-23A Guragaon-122017 Haryana India b Department of Mechanical Engineering National Institute of Technology Kurukshetra-136019 Haryana India c Department of Mechanical Engineering YMCA University of Science amp Technology Faridabad-121006 Haryana India ARTICLE INFO ABSTRACT Article history Leaf springs in vehicles are used to absorb store and release energy. During this cycle Received March 6 2014 stresses induced in the springs must not exceed design stress in order to avoid settling Accepted 23 August 2014 Available online or premature failure. Number of experiments are done in order to determine the 15 October 2014 stresses load rate and deflection which involves lot of time and cost. Today the Keywords technologies in leaf springs are changing gradually therefore new tools are required Static Structural analysis to keep aligned with worldwide technological requirements. The work presented in Leaf springs Computer Aided Engineering this paper provides a CAE solution to static analysis of 65Si7 leaf springs used in light CAE commercial vehicles LCV s . A practical model of leaf spring used in LCV has been 65Si7 taken into consideration for this study. It has been experimentally tested for Load rate deflection stress and load rate on a full scale leaf spring testing machine. A static structural CAE analysis of leaf spring has been done under similar loading condition. The CAD model of the leaf spring has been prepared in solid works and analyzed using ANSYS. Using CAE tools ideal type of contact and meshing elements have .
