Study & Analysis of Structural Behavior of Front Suspension Rear Shackle Bracket

This paper reviews work done in the area of Design & optimization of Suspension Shackle Bracket by FEM. Shackle Bracket is part of leaf spring mechanism/ assembly, which accommodate leaf deformation, when subjected to operational load. Simple, to allow for length changes of a leaf spring. A leaf spring suspension is a pretty simple thing, leafs position the axle under the vehicle, and supports the weight of the vehicle. As a leaf spring flexes up or down, its length from eye to eye changes. Since one end is mounted solidly, and can’t move, all the length change happens at one end, which has a shackle between the spring and frame to allow for movement. Provides support for front spring and Transfers forces to frame. Shackle bracket is made from casting and forming process. In this paper shackle bracket structure is used for study the structural behavior of main whole structure under different working load conditions. Pro-E software is used for 3D modeling of structure & Nastran software is used to carry out Nonlinear & linear Static analysis of structure to find out the maximum stresses & deformation.
