The triple startype compressor is a new type of reciprocating compressor with good dynamic performance, and its main drive system is essentially composed of the majorminor linkage. In this paper, the main drive system of the triple startype compressor and Wtype compressor is studied in order to compare their dynamic performance. Their dynamic simulation models are established and solved in the same working condition by using ADAMS software. Their radial displacement of crankshaft journal center and the trajectory of their crankshaft journal center are obtained. The calculation results show that compared with the Wtype compressor, the response amplitude of crankshaft journal center of the triple startype compressor is reduced by 12.36%, the bearing counter force is reduced by 44.62%. The dynamic performance of the triple startype compressor is better than the Wtype compressor’s.
