摘　　要：运用微分方程理论和不等式理论,对平方阻尼非线性系统的抗冲击性能进行了理论研究,推导了抗冲击性能指标J1和J2之间的关系,获得了系统达到最优抗冲击性能的条件,导出了最优参数的解析表达式。The anti-shock performance of quadratic damping nonlinear system was researched by using the theory of differential equation and inequality.The relationship between the performance indexes Jj and J2 is derived and the condition under which the system has the optimum anti-shock performance is obtained. Based on the resuh of the research, the optimum parameters are presented.
