TH6350加工中心试验模态分析

Test modal analysis of TH6350 machining center

介绍TH6350型加工中心的试验模态分析方法,采用相关双输入伪随机信号激励法进行试验,并应用模态分析软件以多自由度曲线拟合技术辨识其模态参数。所得结果为进一步的理论分析及结构优化设计提供指导。

In this paper,it is introduced that test modal analysis method of the TH6350 machining center ,which using the correlative double input of pseudorandom signal. the modal parameters is identified using the modal analysis software and the curve fitting techniques for the multi-degree of freedom mechanical system. The obtained results in this paper will help the further theory research and the optimal design of the structure.
