Through the theory study on linear compressor leakage and based on the theory,we conduct the piston offset theoreti-cal derivation process,analyze the influence factors of compressor offset and conclude that the piston offset is determined by the differential pressure at the two ends of the gap in the compressor and the axial stiffness of the spring.Thus we establish the physi-cal model of the linear compressor about offset research by PUMPLinx software,make use of the numerical simulation method to obtain the compressor internal pressure,mass flow and changes of the piston displacement at the initial stage and further reach a conclusion that the influence factors of offset phenomenon on linear compressor.
