摘　　要：针对目前快速复位型冲击隔离器设计的难点,提出快速复位性指标新的数学表述,将时间由指标函数转变为约束变量;分析了不同约束条件下单自由度线性系统冲击响应的特点,得到相应的位移峰值和加速度峰值解析表达式;在此基础上将设计问题化为10个约束和目标都为非线性函数的非线性规划方程,并用SQP方法对其进行求解;对求解后的结果进行了分析,得出了快速复位型冲击隔离器的一些重要特性与设计规律;最后建立了可工程使用的图解设计法。研究填补了冲击隔离理论在快速复位性方面的空白,具有重要的理论意义与工程应用价值。For rapid recovery shock isolator design,a novel expression was addressed to change time from an index function to a restraint variable.Equations of displacement and acceleration peaks were derived through shock response characteristic analysis of a SDOF system with different constraints.Then,the design problem was modeled into ten programming equations whose constraints and index were both nonlinear.They were calculated by means of SQP method,and the results provided insight into some important characteristics and design principles of a rapid recovery shock isolator.In the end,a graphical design method was put forward for application.The results represented a preliminary step in the development of theory of rapid recovery shock isolation,and they were valuable in application.
