Investigated NVH problem of a Brake Squeal using HYPERMESH, PERMAS and MATLAB programs. Main task was to perform dynamic Eigenvalue Analysis and study of damping factor using multiple numerical simulations. The target of this project was to reduce the squealing of brake disc and to make the design more Robust & Reliable. Therefore, several Design Optimization methods and FEM calculations are implemented.

The main goal of this thesis is to develop realistic Finite Element model which solves thermo-mechanical multi-physics problem of Silicon Carbide roll. The mechanical properties are determined by Three Point Bending test at room temperature and at high temperature condition. In addition, micro-structural study is also done to analyze the presence of defects of the material using X-Ray Computed Tomography. The design results found are reliable and can be used further for weight optimization process.

The task of the project involves FEM Design and Development of a vehicle model with HYPERMESH morphing Technique and the Finite Element Calculation is done using LS-DYNA. The results were then visualized and analyzed using Animator and LS-Prepost. Further, the optimization is done using LS-Opt to improve the non-linear crash behavior of the model.

Task of the project is to simulate the heat flow in 2-Dimensional and 3-Dimensional Cylindrical Co-ordinate System for the Ceramic Work Rolls in Cold Rolling Process. The Finite Element Calculation is done using MATLAB and FORTRAN programs.
