摘要
精密传动系统中传动部件产生的弹性扭转变形将导致机械谐振的形成,对系统的动态性能产生较大的影响,甚至导致系统不稳定,损坏系统的精密传动部件。以高精度少齿差减速器为传动部件,构建精密交流伺服驱动系统,建立了精密传动系统动力学模型。针对系统响应影响参数多,计算复杂的问题,提出了基于转动惯量、刚度系数、传动比以及传动误差的多参量灵敏度分析方法。该方法可以为精密传动系统设计提供理论上的参考依据。
The elastic torsional deformation of the transmission parts in the precision transmission system will lead to the mechanical resonance, it has a great impact on the dynamic performance and even lead to the instability and failure of precision transmission components. The precision AC servo drive system with high precision and small teeth difference reducer is built, and the dynamics model of the precision transmission sys- tem is established. Due to the problems of multiple parameters and complicated calculations, a multi - parame- ter sensitivity analysis method is introduced that is based on rotational inertia, stiffness coefficient, transmission ratio and transmission error. A theoretical reference for the design of precision transmission system can be pro- vided by this method.
