当有阻尼多自由度线性弹簧、质量系统同时受到两种以上不同的激励时．根据运动力学基本定律分析响应过程，得到各个物理量之间存在着的基本数理关系。由此推导出系统的基础力平衡方程。将部分典型的振动、冲击激励函数分别代人方程，求出无阻尼系统的对应的响应函数。对比分析响应函数的组成与变化特点。将部分典型的激振函数分别代入方程，求出有阻尼系统的对应的响应函数的移相型影映振动函数部分。
When there is a damped multi-degree-of-freedom linear spring, the mass system is affected by more than two different stimuli simultaneously. According to the basic laws of sports mechanics, the response process is analyzed, and the basic mathematical relations between the various physical quantities are obtained. Derived from the system of basic force balance equation. Part of the typical vibration and shock excitation functions are respectively substituted into the human equations to obtain the corresponding response function of the un-damped system. Comparative analysis of the composition and characteristics of the response function. Part of the typical excitation functions are substituted into the equations to obtain the phase-shifted mapping function of the corresponding response function of the damped system.
