本文将逆虚拟激励法(IPEM)用于求解平稳随机振动的荷载谱识别问题。已知部分结构应变(或部分应变及部分位移)响应的自谱与互谱,反求多点激励间的自谱与互谱。
In this paper, inverse virtual excitation method (IPEM) is used to solve the problem of load spectrum identification for stationary random vibration. It is known that the self-spectrum and cross-spectrum of partial structure strain (or partial strain and partial displacement) response and the self-spectrum and cross-spectrum between multi-point excitation.
