摘要
采用实验模态方法进行测试,测试了3个因素在不同水平时固定结合面的动柔度值,通过对固定结合面有限元仿真分析对实验模态测试结果进行了对比验证,结果表明两种方法所得结果基本吻合。设计了螺栓预紧力矩、连接螺栓个数以及固定结合面介质种类等3个因素的L9(34)的正交试验,计算了三个影响因素对结合面动柔度值的影响效果,进行了排序。研究的方法与结果可为进一步研究结合面动态特性提供参考。
Using experimental modal test method,test of 3 factors at different levels when the fixed combination of surface dynamic flexibility value,based on the fixed joint finite element simulation analysis of experimental modal test results were verified.The results show that the results of two methods are in good agreement with.The orthogonal test of L9(34)of 3 factors including bolt pretightening moment,number of connecting bolts and media type of fixed joint surface is designed.The influence of three factors on the dynamic compliance value of the joint surface is calculated.The method and result of this study can provide a reference for further study of the dynamic characteristics of the surface.
