摘　　要：提出将气囊隔振器应用于舰艇推进电机的隔振,根据隔振系统的力学模型以及气囊隔振器的特性,计算了推进电机隔振装置在电机反扭矩作用下和船体倾斜情况下系统的位移,以及系统的固有频率。为提升系统的稳定性,研究了不同支撑高度下系统的位移和固有频率的变化情况。Air spring is tentatively used as the mounting for marine propulsion mechanical machine in this paper.The motion equation of the air spring mounting system is derived based on the stiffness model of air spring.And the machine displacements induced by output torque and ship rolling,as well as the system natural frequencies,are calculated with the motion equation.To enhance the stability,i.e.reduce the foregoing displacements,the effects of different mounting position on the machine displacements and system frequencies is studied.
