【Abstract】 On the background of isolation system of a refrigerator compressor, a new mechanical model of the compressor was proposed, and applying substructure mobility approach, the formula of transmissibility of the isolation system was derived. Then on the basis of the known formula, some parameters of the isolation system were optimized by genetic algorithm. Furthermore, numerical simulations and experiments for the theoretical formula and the results of optimization were carried out respectively, the results of experiments and optimization prove the accuracy of theoretical analysis. All results have the applied value in engineering.更多还原
