【摘要】：为了提高胶印机高速印刷条件下的动态特性,针对胶印机齿轮传动系统动力学问题,建立了多级平行轴齿轮传动系统动力学模型,并对其进行动态优化设计.首先,描述了齿轮传动系统的时变啮合刚度、静态传动误差、啮合阻尼、动态啮合力和滚动轴承刚度表达式,并利用集中参数法建立了多级平行轴齿轮传动系统动力学模型;然后,运用Runge-Kutta法对齿轮传动系统动力学方程进行数值求解;最后,采用序列二次规划法对齿轮系统进行参数优化,并对其进行齿廓修形.数值计算结果表明,优化后齿轮系统的动态特性在啮合刚度、单齿载荷、动态啮合力、动态传动误差和滚筒相对滑动速度方面都有提高,为解决胶印机高速印刷条件下动态特性不良问题开拓了一条新途径.
[Abstract]:In order to improve the dynamic characteristics of offset press under the condition of high speed printing, the dynamic model of multi-stage parallel shaft gear transmission system was established and the dynamic optimization design was carried out in order to solve the dynamic problem of offset press gear transmission system. Firstly, the expressions of time-varying meshing stiffness, static transmission error, meshing damping, dynamic meshing force and rolling bearing stiffness of gear transmission system are described, and the dynamic model of multi-stage parallel shaft gear transmission system is established by means of lumped parameter method. Then, the dynamic equations of gear transmission system are solved numerically by Runge-Kutta method. Finally, the parameters of gear system are optimized by sequential quadratic programming method, and the tooth profile is modified. The numerical results show that the dynamic characteristics of the optimized gear system are improved in terms of meshing stiffness, single tooth load, dynamic meshing force, dynamic transmission error and relative sliding speed of the drum. In order to solve the problem of bad dynamic characteristics of offset press under high-speed printing conditions, a new way is developed.
