摘要

隔振器作为舰用设备抗冲击的重要防护手段被广泛应用，而带有限位功能的隔振器在特定情况下所产生的二次冲击问题也是目前抗冲击设计所关注的主要问题之一。带有限位功能的隔振器可能会产生二次冲击效应，因此合理选择限位器刚度及设置限位位移，以确保冲击响应允许的条件下合理选择两种参数。同时，在研究设备抗冲击性能时是否考虑设备安装基座刚度，对设备抗冲击研究结果影响较大。以单自由度和双自由度无阻尼系统为研究对象，基于分段函数研究的方法，分析基座刚度对冲击响应的影响及不同限位器刚度及限位距离对冲击响应的影响，提供更为准确选择限位隔振器的依据。

Abstract

The use of vibration isolator is an important means for improving the anti-shock performance of marine experiments, and its second impact problem under certain condition is one of the main concerns in impact analysis.Therefore, it is necessary to choose reasonably restrictor parameters, such as the stiffness of restrictor and the restricted displacement, to fulfill the allowable impact response condition.At the same time, the consideration of the rigidity of installation foundation has a great influence on the anti-shock performance of marine experiments.In the paper, an undamped system with one degree of freedom and an undamped system with two degrees of freedom were taken as the analysis objects.Based on the piecewise function method, the influences of foundation stiffness on impact responses and different restrictor parameters were discussed.The results provide a more accurate basis for choosing vibration isolators.
