摘要

The optimization of components in vehicles becomes essential to reduce the cost and increase the durability along with the comfort due to the increase in demand. The current study is focused on investigating the structural behavior and optimizing the automobile air conditioning compressor mounting bracket while exposed to vibrations conditions. A CAD model of bracket was generated using reverse engineering and then analysis was performed using Finite Element Method (FEM) tools like Hypermesh and Optistruct. During modal analysis, 359.91 Hz, 625.44 Hz, and 914.41 Hz were identified as the natural frequencies and also, shows a critical stress concentration when the frequencies of excitation matches with the natural frequencies. The structural optimization reduces the mass of bracket by 9.4% and also, shows improvement in stiffness without any effect on performance of bracket. Moreover, redesigned bracket shows a 22% reduction in the value of Von-mises stress under harmonic excitation, that makes it more resilient to fatigue and increase the durability. The improvements in the bracket design shall be useful in the industries to meet the standards of performance and satisfaction of customer during dynamic environments.
