提出舰船单层隔振系统中采用以聚氨酯泡沫为材料的限位器进行设备限位,研究塑性限位器各参数对舰船设备最大加速度和最大相对位移这两个重要指标的影响,提出确定限位器参数理论方法,采用Matlab软件将塑性限位器理论量化方法和设计计算程序用于单层隔振系统模型,并进行冲击实验,证明该理论方法的正确性。

A strategy adopting polyurethane foam plastic restrictors to restrict the displacement of shipboard equipmentin the single- stage vibration isolation system is proposed. The influence of parameters of the plastic restrictors on themaximum acceleration and maximum relative displacement of the shipboard equipment is studied. A theoretical method fordetermining the parameters of the restrictor is presented. Matlab code is used to quantify the plastic restrictor theory. Themodel of the single-stage vibration isolation system is designed and its computation program is done. Shock experiments arecarried out to prove the correctness of the theory.
