摘　　要：以多层隔振系统质量块(刚体)空间一般运动的坐标变换,系统的动能、势能和阻尼耗散函数,系统的拉格朗日方程为理论基础,对系统的运动微分方程进行了严格的数学推导,得出适用于质量块之间或质量块与基础之间具有6个相对运动自由度的多层隔振系统的运动微分方程组。该方程组对现有方程组有较大的改进,可应用于舰船的隔振降噪浮筏装置。The paper is based on the coordinate transformation of space general motion for mass blocks(rigid bodies)and Lagrange equation of multi layer vibration isolation system.A strict mathematical derivation on the differential equation of the motion for the system with six degrees of freedom of relative motion between mass blocks(including base)is carried out.The equations are different from the same kind of equations in the reference literatures.They can be used in the floating raft of ships in order to isolate vibration and decrease noise,also used in design calculation of the multi layer vibration isolation for dynamic machinery and precise instruments on dry land.
