Analysis of suzuki mehran leaf spring for static and dynamic finite element analysis (fea) of leaf spring


  • Muhammad Amin Sarhad University of Science and IT Peshawar




The current study is focused on analysis of Suzuki Mehran leaf spring for static and dynamic loading conditions. The CAD model of spring was prepared in solid works with the description as reported in [1]. Meshing and FEM modelling was done in Ansys Mechanical environment. The current work is presented in two section, the static analysis and dynamic case. The loading considered for static analysis is associated to a scenario when the vehicle is turning in a circular path with turning radius of 10m at a speed of 50m/s. While for dynamic loading, a transient boundary condition is applied for a bump profile as given in [2]. Before the calculations, a mesh sensitivity analysis is performed to optimize the grid size which is followed by actual calculations. In static case, stress analysis is performed for principal stresses and von misses stresses. Factor of safety based on ultimate strength is found to be 1.5 under static loading. In transient analysis, the stress histories are recorded and presented here for reference.
