Dynamic analysis of compressor mounting bracket of automobile air conditioning system

Abstract

With the automotive air-conditioning industry aiming at higher levels of quality, cost effectiveness and a short time to market, the need for simulation is at an all time high. In the present work, the use of dynamics analysis technique is proposed in the simulation of the automobile compressor mounting bracket for the vibration loads. The mounting bracket has been analyzed using the standard testing conditions. The results revealed that the compressor mounting bracket may fail due to resonance in dynamic analysis, but in the static analysis, resonance cannot be predicted under the same magnitude of load. Therefore, dynamic analysis gives a realistic method for its design validation. With the use of the above methodology, a new compressor mounting bracket is analyzed and optimized. Also, the importance of certain ribs or stiffeners is studies using the proposed methodology.
