齿轮轮齿接触力仿真研究

Simulation Study on Contact Stress of Gear Footh

基于虚拟样机技术,用ADAMS软件建立了某型齿轮系统力学模型,进行了仿真研究,模型中用二维曲线-曲线接触定义齿轮副约束,并计及了摩擦力的作用。仿真结果与理论分析结论一致,证明了在齿轮系统中应用此种方法建立模型的正确性。得到了某一特定传动条件下单对齿轮轮齿法向力及齿间摩擦力的变化规律曲线,从而可以指导齿轮系统的设计和优化。

A mechanics model of a gear system is build and simulated in ADAMS based on the virtual prototype, in which gear pair is defined by curve-curve contact and friction is considered. The coherence of the simulation result and the academic data proves that the method of using this contact in gear system is correct. That the curves of the normal force and friction force between two corresponding gear teeth in a given condition can supervise the design and optimization of gear system.
