free vibration mode

基本解释

This paper focuses on free-interface component mode synthesis methods for damped vibration systems.
研究了阻尼振动系统的自由界面子结构综合法。
The damping properties in the free vibration of the system were extracted by complex-mode analysis technique.
通过复模态分析得到以超越方程形式表达的系统自由振动阻尼特性的解析形式。
Processing the response signals by using the random decrement technique, a unique corresponding to each mode is obtained, which represents a free vibration response of the structure.
应用随机减量技术对响应信息进行处理，相应于结构的每一振型可得到一条独特的随机衰减曲线，该曲线代表结构自由振动响应。
