摘要
运用多体动力学理论建立了齿轮多体系统模型,该模型由可沿圆周转动的轮齿、弹性单元和齿轮本体组成,轮齿和齿轮本体虽然仍是刚体,但它们以转动弹簧-阻尼器相连接。采用了迟滞接触力模型分析轮齿间的啮合,为了验证该模型,分别以该模型、有限元模型和其他文献的模型研究单对渐开线直齿圆柱齿轮的啮合过程,对比分析表明:该模型的计算结果更接近于有限元方法,非常适用于齿轮系统的多体动力学分析。
Based on multibody dynamics method,a new dynamics model of multibody geared system was presented.This model consisted of the gear body,circumferentially rotatable rigid teeth and elastic elements composed of rotational spring-damper combinations.The teeth and the gear body were still regarded as rigid bodies,but they were connected with each other by elastic elements.Besides,a complaint contact force model was utilized to compute normal contact force during meshing.The contact between the single side flanges of two spur gears was investigated via three different methods of existing approach,the newly built model and a full FEM simulation.Comparisons indicate that the results of the model herein are closer to the accurate results of FEM and the newly built model is very suitable for modeling multibody geared systems.
