The dynamic behaviors of an elastic crankshaft-rolling bearing system in a W-type piston compressor are studied by ADAMS, special software for dynamical simulation. Firstly, the finite element model of the elastic crankshaft is established in ANSYS, a kind of Finite element software. Secondly, a statically indeterminate problem for rolling bearing is studied to obtain the formula between the applying load and the relevant displacement of the bearing, force method and Hertz theory are used to solve the statically indeterminate problem. The numerical solution of the applying load and the relevant displacement of the bearing are acquired. Finally, the dynamical simulating model of the elastic crankshaft-rolling bearing system is built in ADAMS. The calculation results are available to improve the dynamic performance of reciprocating compressor and to design the main bearings.
