摘要
本文提出一种基于光滑样条函数的动态载荷识别方法。该方法克服了传统的频域法和时域法需要事先测定系统频响函数或模态参数的限制,只需要系统的少量物理参数就可以达到载荷识别的目的。文中设计了一个十自由度的系统,算例表明了该方法的有效性。
A novel force identification met hod is proposed.This method,which does not require any frequency response functi on(FRF) or modal parameters,differs from traditional frequency domain and time d omain methods.Only some physical parameters and responses are involved in this m ethod and the numerical simulation of a 10 DOF system has demonstrated the effe ctiveness of this method.
