4.2. The meshing of the steel spring
After the preparation of the geometrical model and insert material properties, the meshing has performed on the geometrical model of steel leaf spring. Meshing describes the division of parts of the entire model into small elements. The main objective of meshing is to obtain the accuracy of the analysis. The minimum mesh element size of 5 mm has considered for mesh generation as leaf spring contains sharp edges and curves with the objective of high accuracy. The fine meshing of the geometrical model is shown in Fig.4.2.
4.3. Boundary conditions
For the boundary condition, both ends of leaf spring are designed as eye shapes so that both ends are connected to the frame of the vehicle and a simple pin has used to connect leaf spring to the frame so that eye of leaf spring free to rotate but it has restricted to translate and rotate in all other directions. The spring is allowed to move only in x-direction when the load has applied and all other side is restrained to move. As finite element of steel leaf spring has performed by ANSYS software, the load applied at the center of the steel spring in y-direction and stress-induced in the steel spring.
4.4. Stress Analysis of Steel Leaf Spring
The Initial load has applied on the spring that was 1000 N. After that 2000N, 3000N, 4000N, 5000N and 5400 N (Full Load) has applied in the spring. The stress values at different loads have shown in Table 4.1.
It was found that maximum stress developed at the outer edge of the steel leaf spring. The stress analysis plot during static analysis of steel leaf spring under different loads is shown in Fig.4.3.
