【摘要】 冲击引起的振动与波是舰船破坏的主要原因之一。采用空间多刚体动力学基本理论,建立非线性双层抗冲隔振系统的数学力学模型,推导出适用于一般的双层抗冲隔振系统的牛顿-欧拉方程。然后以一个水泵设备的双层抗冲隔振的例子进行数值计算。更多还原

【Abstract】 One of the main reasons for destroy of marine equipment is the vibration and wave caused by shock.The mechanical model of the multi-stage isolation system with nonlinear protection devices is established,and the nonlinear differential equations are deduced by applying the multi-body dynamics theory that is Newton-Euler’s Equations applicable for the general multi-stage isolation system.At last taking a water pump as an example,it is numerically solved.更多还原
