摘　　要：转子不平衡质量的存在是影响电机工作稳定性的一大关键因素。为降低动平衡测量系统固有频率对应信号对测量结果的影响,需要控制固有频率的大小,使其远离测量时转子的旋转工频。而测量系统支撑部分的簧片是影响系统固有频率的重要因素。因此,首先建立起转子-支撑系统动力学模型,分析支撑系统的固有频率和质量对支撑系统灵敏度的影响。其次分析支撑系统簧片的各尺寸参数与系统固有频率之间关系,从而设计最佳簧片尺寸。最后研究不同固有频率支撑系统下转子的振动响应特性。研究结论有助于提高转子动平衡机的测量精度和稳定性。The existence of unbalance mass of rotor is a key factor affecting the stability of motor operation.In order to reduce the influence of the signal corresponding to the natural frequency of the dynamic balance measurement system on the measurement result,it is necessary to control the natural frequency and keep it away from the rotating power frequency of the rotor during the measurement.The spring of the support part of the measurement system is an important factor affecting the natural frequency of the system.Therefore,in this paper,a dynamic model of the rotor-support system was established,and the influence of the natural frequency and mass of the support system on the sensitivity of the support system was analyzed.Then,the relationship between the size parameters of the spring of the support system and the natural frequency of the system was analyzed,so as to design the best reed size.Finally,the vibration response characteristics of rotors under different natural frequency support systems were studied.The conclusion of this work is helpful to improve the measurement accuracy and stability of the rotor dynamic balancing machines.
