Rotational imbalance is one of the factors that affect performance and reliability of rotary compressor. The rotor system of the compressor is taken as a study object. Both the inertia force and the gas force are taken into account to build a mechanical model. The mechanical model is used to deduce the relation between the characteristics of balancer and rotational angle of the crankshaft. Residual imbalance function of the rotor system is constructed to optimize the parameters of the balance. Vibration experiment of a compressor is performed for validating the method.
