Structural FE analysis on an integral bus is performed, in which optimal design of multiple performance objectives of structural strength, vibrationmodalfrequency and mass is researched.
This paper presents a synthesized model updating method using the modal parameters and frequency response functions(FRF) extracted from the vibration test data.
文章提出了一种利用模态参数和由振动试验数据求得的频响函数来进行模型修正的方法。
