The generalized Ruzicka system is introduced which has a wide application in actual engineering system such as railway vehicles and road vehicles. Through the establishment of the differential equations of the generalized Ruzicka system, the analytical formula of the transmissibility of the system with harmonic input is derived and the simple vibration isolation system and Ruzicka system can be taken as the special cases of the generalized Ruzicka system. Finally, the 1/4 railway passenger car body model is taken as an application example. The harmonic vibration isolation behavior of the Ruzicka and generalized Ruzicka system are studied and the effects of the parameters of the systems are analyzed.
