通过数值计算，研究后峰锯齿次冲击下，非线性参数、阻尼对立方非线性包装系统产品损坏边界的影响规律．得出了使响应加速度幅值最小的最佳阻尼。 By numerical calculation, the effect of non-linear parameters and damping on the damaged boundary of cubic nonlinear packing system is studied under the influence of secondary saw-tooth secondary impact. The best damping that gives the lowest response acceleration amplitude is obtained.
