摘要:
针对远航舰船异步电机轴承经常烧毁的问题,以一台Y100L-2型电机为研究对象,采用有限元法建立电机转子三维导热模型,对电机轴承在不同的运行状态下的电机转子三维温度场进行仿真,并结合电机轴承故障的试验进行了分析。分析结果显示,不论轴承是否有故障,电机端盖温度均是沿径向从内到外逐步下降;在端盖轴承座正对部位,温度变化缓慢,但是从轴承外径继续向外,端盖温度下降迅速;负荷变化对电机端盖温升的影响远远大于轴承损坏对端盖温升的影响;不能仅仅凭借端盖表面温升来对相应轴承状态进行判断,可以通过同一种负荷条件下端盖表面温升的变化对轴承状态进行判断。
Abstract:
Aiming at resolving the problem of the fault of motor bearing on warship,a three-dimensional mathematical heat transfer model has been built according to the structure of Y100L-2 asynchronous motor.The thermal fields of rotor with a fault were simulated under different load,and a temperature rise experiment of motor with a fault bearing has been done.The results show that the temperature of the part that contacts the motor bearing is higher than other parts and changes little,and the temperature...
