Triangle transformation course is employed to simplify the shock input spectrum of equipments and the shock resistance shielding system is simulated with the finite element method.In time domain
impulse load is loaded on the marine power unites integrally first
then loaded on turboset and the gearcase respectively.Through the comparison of different loading methods
it is found out that the dynamic response of the turboset is more serious than the gearcase when loaded integrally;both the dynamic response of the turboset and that of the gearcase when loaded respectively is more serious than that of the power unite when it is loaded integrally;the shock resistance shielding system of power unite is an ensemble
the effect of its shock resistance and isolation is more obvious when it is loaded integrally
and that can resist shock and vibration more effectively.
