摘要
从优化的角度出发,利用遗传优化算法得到频域载荷谱,使得其产生的响应谱与实际的测量结果之间的误差足够小,这样可以认为所得到的载荷谱也就反映了实际的激励,即达到了载荷识别的目的,仿真结果说明了这种优化方法的有效性。
This paper proposed a new method of load identification based on optimization theory, the load spectrum is calculated by genetic algorithm, if the error between responses produced by this calculated load and have been measured is small enough, the optimized load spectrum could be considered as the real excitation, the numerical simulation result shows the effectiveness of this optimization method.
