Modal Analysis of Assembling Condition for the Air Conditioning Compressor Bracket of a Certain Automobile

Automotive air conditioning compressor bracket connects the compressor and engine, and make its long-term vibration in the bad environment, which will cause the compressor can't work smoothly, safely and reliably, therefore the design rationality of automotive air conditioning compressor bracket, directly affects the performance of air conditioning, in turn, affects the vehicle harshness (NVH) performance. So analyze the vibration performance of air conditioner compressor in the design phase is particularly important. This article analyzed the modal of the air conditioning compressor bracket based on the finite element method, and carried out the structure optimization for the bracket, and finally anticipated effect has realized for the mode improve.
