以东风４Ｄ客运机车牵引从动齿轮为例，依据齿轮加工刀具参数及其它有关参数，基于齿轮啮合原理自编软件，自动绘制了机车牵引齿轮的齿形，用Ｉ－ＤＥＡＳ软件对该齿轮进行了静动态分析，不仅获得了各种工况下齿轮受力时轮齿部分的应力及变形，也获得了时变外载作用下的动力响应，为设计提供了有价值的计算结果．
Take Dongfeng 4D traction locomotive traction driven gear as an example, according to gear processing tool parameters and other relevant parameters, based on the principle of gear meshing software compiled automatically draw locomotive traction gear tooth shape, using I-DEAS software on the gear The static and dynamic analysis not only obtained the stress and deformation of gear tooth under various working conditions, but also obtained the dynamic response under the time-varying external load, which provided valuable calculation results for the design.
