A Method of Dynamic Load Identification

Fu Zhifang Rao Zhushi Zhou Haiting (The State Key Lab.of Vibration, Shock & Noise)  
A method using inverse optimizing system analysis to identify a dynamic load is presented, which can reduce arithmetic errors and avoid arithmetic failure produced by the ill condition of the FRF matrix in inverse operation of the matrix. Thus, the precision of identification can be raised. This method provides an efficient way for dynamic load identification, especially for impact load which has the wide frequency bandwidth.
