A method for calculation of the efficiency of vibration isolating systems, which are used in self-propelled machines, is presented. The influence of parameters of vibration isolating systems (masses and stiffnesses of foundation, load and elastic elements of vibration isolators, losses of oscillatory energy in elements of system) on efficiency of vibration isolation is determined. Good agreement is found between theoretical and experimental results. Results of experimental research for vibration isolating systems, which are used in real machines (excavator and tractor), are presented.
