直齿圆柱齿轮动力学特性分析与ADAMS仿真研究

INVESTIGATION ON DYNAMIC CHARACTERISTIC OF CYLINDER GEARS AND SIMULATION BASED ON ADAMS

在考虑时变啮合刚度、啮合阻尼、齿面摩擦等因素的基础上,采用集中参数法建立了圆柱齿轮传动系统平移-扭转耦合动力学模型。根据齿轮箱设计参数,使用龙格-库塔法求得各齿轮的振动位移,计算了齿轮副的动态啮合力。并在Adams中建立齿轮传动系统的多体接触动力学模型并进行仿真,获得齿轮啮合传动过程中的动态啮合力和振动位移、振动速度。通过台架试验,测量齿轮传动系统的振动加速度,采用数值积分计算振动速度和位移,并分析其振动特性。结果表明,在齿轮的振动速度与位移方面,集中参数求解结果与实验数据具有良好的一致性;啮合力方面两种方法均得到与理论计算值一致的结果,验证了采用两种方法对比分析研究方法的可行性。

Translational-rotational coupling dynamic model of the cylinder gear transmission system was established using the lumped-parameter method,which considered the time-varying mesh stiffness,mesh damping,friction of tooth surface.According to the design parameters,Runge-Kutta was used to get the vibration displacements of each gear and the mesh force of the gear pair. The multi-body contact dynamics model of the gear transmission system was built based on ADAMS,and dynamic mesh forces and vibration displacement and vibration velocity were obtained by the simulation. With the test plan,the vibration acceleration of the gear transmission system was measured,and then the velocity and displacement could get by numerical integration to analyze the vibration characteristics. The results show that in terms of gear velocity and displacement,the test data and theoretical analysis results have good consistency,which verify the feasibility of comparative rearch of the two method.
