转子扭振与故障模拟多功能试验台设计

摘要

为改进普通转子试验台功能单一的不足,设计一套转子扭振与故障模拟多功能试验台.基于有限元分析软件ANSYS,对转子系统进行模态分析,经过反复计算与修改,完成转子的结构尺寸设计.针对转子圆盘、碰摩试验支座等组件设计特定外形,并开发专用的数据采集与分析应用软件.该平台可用于转子动力学分析与转子多故障的模拟和振动测试分析.%A multi-functional test bench for rotor's torsional vibration and fault simulations was designed to overcome the defect of unitary function of the traditional rotor test benches. Based on the finite element analysis software-ANSYS, modal analysis was carried out for the rotor system. Design of the structural geometry of the rotor system was completed after several simulations and modifications. According to the special shapes of rotor disc, rubbing test support and some other components, special software for data acquisition and analysis was developed. This test bench can be used for rotor dynamics analysis, multiple fault simulation and vibration test and analysis of rotor systems.
