Response Analysis and Load Optimization of High Temperature Reactor-Pebblebed Modules Main Helium Blower Rotor System
摘要
Abstract
In response to the parameter design and performance optimization of radial active magnetic bearings in the magnetic bearing rotor system of the high temperature reactor-pebblebed modules(HTR-PM)main helium blower,the system boundary conditions were sorted out by applying the expected characteristics to dynamic analysis.Meanwhile,the transient analysis method was used to simulate the influence of bearing control parameters on the system's response and loads,and the ideal control parameter range that satisfied the design expectations for the rotor system was obtained.Subsequently,based on the dynamic response results of the rotor under different rotational speeds,equivalent unbalance,bearing stiffness,and bearing damping within the parameter range,the influence between the control parameters and rotor response was analyzed.According to the obtained patterns,the optimal control parameters for the magnetic bearing-rotor system at each frequency band within the operating frequency range were determined.Finally,the variation laws between the response displacement,bearing load,equivalent stiffness,and damping ratio of magnetic bearing-rotor system under different working conditions and performance requirements were summarized.A control scheme for selecting appropriate control parameters based on the real-time operating frequency of the rotor was designed and verified.The results show that when the control parameter selection meets the optimization conditions,this method is able to suppress the overall amplitude of the unbalanced response,eliminate the resonance peaks,and optimize the maximum load at the bearings while achieving the working requirements of the rotor system.关键词
