摘要为了提高舰载设备的抗冲击性能，改善限位参数不匹配造成的二次冲击问题，建立了八参数可独立设置的带限位隔振系统数学模型，利用四阶龙格库塔的方法进行冲击仿真计算，并与冲击试验结果进行对比，分析了限位器参数（刚度比，安装间隙）对冲击响应的影响。研究结果表明：当刚度比足够大，存在一个使系统加速度响应取得最大值的特殊间隙，称为共振间隙。共振间隙的存在，增大了系统的加速度响应，加剧了系统的冲击碰撞，但可以通过选择更小的安装间隙，匹配合理刚度比来有效的避免共振间隙现象的产生，进而可以有效的提高舰载设备的抗冲击性能。

Abstract：In order to improve impact resistance of shipborne equipment and ameliorate the secondary impact problem caused by mismatch of limit parameters, the mechanical model with 8 parameters set independently for a vibration isolation system with displacement restrictors was established.The shock simulation computation results obtained with this model and the 4-order Runge-Kutta integration algorithm were compared with those of impact tests.The effects of restrictor parameters including stiffness ratio and installation gap on the system’s shock responses were analyzed.The results showed that when stiffness ratio is large enough, there is a specific gap making the system acceleration response the maximum, it is called resonance gap; the existence of resonance gap amplifies the system’s acceleration response and intensifies the system’s impact collision; but the resonance gap phenomenon can be effectively avoided by choosing a smaller installation gap and matching a reasonable stiffness ratio to effectively improve impact resistance of shipborne equipment.
