摘要
研究了周期双参变激励齿轮系统在摩擦作用下的动力学响应,建立了考虑轮齿时变啮合刚度和齿间摩擦的单自由度扭转非线性振动模型,研究了摩擦因子、重合度、惯量比、刚度因子、阻尼因子、载荷分配系数等参数对齿轮系统非线性振动响应的影响。研究结果表明:摩擦对周期双参变激励齿轮系统非线性振动有重要的影响。
This paper studied the influences of tooth friction on parametric dynamics response of a single-mesh gear pair.A dynamics rotational model was developed to consider this mechanism together with the other contributions of tooth friction and mesh stiffness fluctuation.The impacts of friction coefficient,contact ratio,inertia ratio,stiffness factor,load share coefficient and model damping on the response and long range response were investigated.The effects of time-varying friction moments about the gear centers are critical to non-linear vibration response.
