摘要
基于ADAMS建立了刚—弹耦合齿轮多体动力学模型,并论述了相关参数的选取方法。对基于石川公式的相关计算数据进行拟合,得到了模型中转动刚度的计算公式。利用ADAMS二次开发技术,开发了相应的齿轮模块,解决了模型建模过程过于繁杂的问题。通过实例仿真验证了刚—弹耦合齿轮多体动力学模型的先进性。分析表明:在多体动力学中运用此齿轮模型可获得比传统方法更为精确的结果。
Based on ADAMS, the rigid - elastic model of gear is built and the relevant parameters of this model are discussed. By fitting the data which are calculated using Ishikawa gears stiffness formulae, the rotary stiffness calculation formula in the model is obtained. Based on the ADAMS secondary development technology, the corresponding gear module is developed to simplify the modeling process. A simulation experiment is used to testify the advancement of rigid - elastic model of gear, which indicates that more accurate results can be obtained in multibody dynamics anal- ysis using the rigid- elastic model of gear.
