Present suspension damper for washing machine mainly generates damping forces by coulomb friction. Therefore, the performance of damper lowers by the aging degradation. We propose noncontact damping mechanism using permanent magnet. In this paper, we call newly developed damper which consists of coil spring, magnetic spring and magnetic damper "Composite Damper". In order to realize high-performance damper, we examined the relationship between displacement and damping coefficient of dampers by excitation tests. Then, we expanded the simulation method in the previous report to the case where Composite Damper is installed. Finally, we succeeded in constructing the calculation method for describing the behavior of the drum only from the result of the excitation test.
