升降台铣床动态试验分析李沪曾Ｇ．ｓｎｕｒ徐炳楠通过相对激振测定升降台铣床切削点动柔度矩阵的原理、结果以及模态分析结果，并与切削试验结果对比证明激振试验结果可信，指山建立机床多质量多自山度等效系统模型的必要，探讨了结构非线性之外可能导致动柔度矩阵不对称...
Dynamic Test and Analysis of Lifting Table Milling Machine snur Xu Bingnan By relative excitement, the principle and result of modal analysis of jiggling flexibility of lifting table milling machine and the results of modal analysis are compared with the results of cutting test to prove that the exciting test results are credible. Equivalent system model is necessary to discuss the structural nonlinearity may lead to dynamic flexibility matrix asymmetry ...
