摘要
提出了利用模态分析、谐响应分析以及载荷谱变换来实现遥感器正弦振动试验的有限元方法。简述了模态分析、谐响应分析的功能及其理论基础;说明了常用正弦振动试验载荷谱的形式及其变换方法;研究了结构系统阻尼的实现方法;最后以箱形结构为例,说明该方法的可行性。
A finite element method that modal analysis and harmonic response analysis and load spectrum transformation was used to actualize sinusoidal vibration experiment of remote sensor was proposed.Functions and theory foundation of modal analysis and harmonic response analysis was described.Forms and its transformation methods of usual load spectrum of sinusoidal vibration experiment were illuminated.Structural system damping and its realization method was discussed.The flexibility of the method mentioned above was demonstrated by an analysis of a trunk structure.
