摘要

针对刚体结构的误差影响,将柔性化建模技术应用于减速器传动系统设计。利用ANSYS平台对各零部件进行有限元建模和模态参数计算,通过MNF文件（模态中性文件）替换的方式实现了减速器的柔性化设计,建立了基于ADAMS/View的柔性化减速器虚拟样机仿真模型。利用Step函数拟合了减速器的驱动转速和转矩负载,实现了柔性化减速器动力学仿真,计算和分析了与实际情况更为接近的仿真结果,如输入输出转矩、加速度、动态载荷及3D频谱,为机械传动系统的柔性化设计与精度分析提供了有力参考和依据。

Abstract

In view of the error influence of rigid structure,the flexible modeling technology is applied to drive system design of reducer. The finite element modeling and modal calculating about its parts are carried out by using ANSYS platform,and the flexible design of the reducer is realized through a way of replacing the parts’ MNF file,thus then a simulation model of the virtual prototype of flexible reducer is set up based on ADAMS /View platform. The driving rotational speed and load torque of the reducer are fitted with Step function,and then its flexible body dynamics simulation is carried out. The simulation results that more close to actual situation is calculated and analyzed,such as input and output torque,acceleration,dynamic load and 3D frequency spectrum,all of those provide some strong reference and basis for flexible design and precision analysis of mechanical drive system.
