| 摘 要： | 本文通过两台滚齿机床的模态分析结果证明了相对激振处理为单点激振的可能性。每台滚齿机床都进行两种激振试验,并用HP5423A结构动态分析仪得到差别很小的模态参数。综合这些模态参数验证了所提出的相对激振传递函数。

| Abstract: | The feasibility of treating relative excitation as sigle-point excitation is demonstrated by comparing the modal analvsis results of two types of gearhobbing machine. Two kinds of excitation tests are carried out on either cf the two machines and the close values of modal parameters are given by the HP5423A Structure Dynamics Analyzer, The transfer function of relative excitation developed in this paper is examined by synthesizing the modal parameters. |
