摘要
基于精细积分和状态空间法提出一种新的浮筏隔振装置抗冲击计算方法,并结合德国海军规范BV 043/85通过算例对该方法进行了验算。结果表明本方法具有收敛性和无需解耦的特点,可应用于复杂荷载和多自由度浮筏系统,而且进行数值求解时不受时间步长限制,计算精度高。
A new anti-shock calculation method for raft isolation system is proposed by the combination of precise integration and state-space. The numerical example shows that the method is convergent and needs not to decouple the system. The example also indicates that the new method is not sensitive to time-step and its calculation precision can be controlled easily. So the method can be used in complex load and multi-degree of freedom system.
