立方非线性包装系统在基础振动激励下的响应

The Response on Cubic Non-linear Packaging System Under Oscillatory Surroundings

对振动环境中立方非线性包装系统进行了计算机仿真及分析 ,通过对系统响应的时间历程、相图、Poincare映射及功率谱等的分析 ,讨论了在确定性振动环境中包装系统的动力学行为 。

Simulation and dynamical analysis are performed on the cubic non-linear transit packaging system under oscillatory surroundings in this paper. The dynamic behavior is discussed in detail by analyzing the motion's time history, phase portrait, Poincare map and power spectrum etc., some tentative strategies are further tested for controlling the system's responses.
