Maximum Impact Force and Thermal Characteristic Analysis of Double-decker Catcher Bearing Used in High-speed and Heavy-load Conditions

Abstract

Abstract:

The working performances of two types (A and B) of DDCB under high-speed and heavy-load conditions were studied based on the established rotor-drop test bed. The relevant dynamics models and heating network model were established according to the rotor-drop test bed. For different DDCB parameters, the dynamics responses of rotor and catcher bearings as well as the inner race temperature rise of catcher bearings were analyzed theoretically. Then the relevant rotor drop experiments were carried out. The research results show that type B DDCB is more suitable for high-speed and heavy-load conditions.

Key words: active magnetic bearing, double-decker catcher bearing(DDCB), rotor drop, dynamics response, temperature rise

摘要：

搭建了转子跌落试验台，研究了A、B两种结构的双层保护轴承在高速重载下的工作性能。建立了动力学模型和热网络模型，理论分析了不同双层保护轴承参数下，磁悬浮轴承失效后转子和保护轴承的动力学响应以及保护轴承内圈的温升情况，并进行了相关的转子跌落试验研究。研究结果表明，B结构双层保护轴承更适合应用于高速重载场合。
