介绍振动传递特性的概念 ,通过低量级随机激励下的振动环境试验 ,建立复杂结构的随机激励和随机响应试验结果的快速运行模型 ,利用该模型可以快速地计算结构在高量级随机激励下的响应以达到预测结构响应的目的。通过一个实际模型的随机振动环境试验实例和分析 。
The numerical approach and the test approach, applied in the design and research procedure of system encountered in aerospace, mechanic, civil engineering and etc. , are very important methods. Especially the research method based on the test is more interesting. Recently the meta model modeling method is widely developed so that the test results can be used to improve the calculation efficiency. The paper deals with the prediction of response of vibration test based on the vibration transfer feature. The meta model can be identified by the transfer feature based on a vibration test. Then the response of system under other excitation can be predicted. An example is presented. The results show that the method presented is feasible.
