【Abstract】 The dynamics models provided with zero-mass elements were usually encountered in machine and the structure vibrations,and the superposition method of vibrations were mostly used for their calculation.The method was difficult to avoid some calculation errors,because it couldn’t obtain some orders of the anterior vibrations.The 0.6-standard was demonstrated for compensating the limitation of the method,and thus achieved the requirement of simple calculation and acquired the engineering calculation precision.更多还原
