Rubbing between rotor and stator is a failure whose process is complicate, and great harm. In order to study the effect of friction heat on synchronous full circular response, taking the aeroengine compressor rotor as research object, a nonlinear model of rotor system was established, considering the characteristics of stiffness. The characteristics of friction thermal rubbing of the rotor was studied and numerical simulation was conducted. The calculation were compared with that without friction thermal effect. The results show that the temperature increases nonlinearly with the increase of the distance of relative rubbing point in radial direction, and is equal to room temperature in 30 degree with symmetrical in circumference direction. Considering friction thermal effect, the speed range of synchronous full annular rubbing is integrally reduced, the radial displacement of the rotor is increased, and the stability of the synchronous full annular rub was reduced by the friction thermal effect.%转子和静子碰摩是过程复杂且危害性很大的故障.为研究摩擦热对同步全周碰摩响应的影响,以航空发动机压气机转子为研究对象,考虑其刚度特性,建立了非线性转子系统分析模型,研究了单盘转子摩擦热碰摩响应特性,进行了数值分析,并与未考虑摩擦热效应的碰摩响应进行了对比.结果表明:碰摩处温度径向随相对碰摩点距离的增加呈非线性增大,周向呈对称分布并在30°时几乎等于室温;当考虑摩擦热效应时,发生同步全周碰摩的转速范围整体缩小,转子径向位移增大,摩擦热降低了同步全周碰摩的稳定性.
