Analysis of engine mounting bracket for an automobile using FEA

Abstract

Objectives: The study is conducted to perform the modelling and structural analysis of engine mounting bracket and also examine the vibration isolation using FFT analyzer. Methods/ Statistical analysis: Modelling and analysis of the engine mounting bracket is carried out using solid works software. Static and modal analysis are performed to check the stress, deflection and effect of natural frequencies under loading conditions. The experimentation is also performed using FFT analyzer to check the effect of vibrations on the bracket in horizontal and vertical position. Findings: Analysis was carried out for different materials like natural rubber, neoprene, and silicon rubber. On comparing the results, the silicon rubber found better material as compare to other materials due to its low stress and deflection value and better frequency values. The experiment results shown that in the horizontal position the vibration were less than the vertical position. Application/ Improvements: Silicon rubber is considered better material for engine mounting bracket for vibration damping. This approach also helps us to find out the weak area in early design phase.
