In article the combined method of vibrating isolation and vibrating clearing on an example of the stand of vibrratsionno-shock hardening of longerons of helicopters is considered. The developed dynamic model allows to minimise factor of transfer of forces on the equipment base that leads to reduction of levels of vibration. Rational selection of parametres of model: such as the weight, resulted rigidity, frequency of vibration allows to provide performance of a sanitary code of vibration at designing of the similar equipment.
