摘要

摘要: 以双盘悬臂转子系统为研究对象,建立了含不平衡-定点碰摩耦合故障的动力学模型.在耦合模型中,定点碰摩的碰摩力采用非线性滞回力模型来表征.在数值仿真过程中,采用线性插值法确定碰摩发生瞬时.利用数值仿真的结果分析机匣凸点材料的软、硬特性,凸点的凸出程度对转子碰摩响应的影响.结果表明:当凸点的材料较硬时,转子系统在较低的转速便会产生拟周期运动;对于较为尖锐的凸点,系统响应会表现出周期、拟周期等丰富的非线性动力学现象;转/静子间隙过小时,系统将在较宽的转速区间内产生复杂的非线性振动.

Abstract: The dynamic model for a dual-disc cantilever rotor system with imbalance-fixed point rubbing coupling faults was established. In the coupling model, the rubbing force of fixed point rubbing was characterized by nonlinear hysteretic force model. In the process of numerical simulation, the moment of rubbing happening was estimated by linear interpolation method. The results of numerical simulation were used to analyze the influences of degree of hardness, softness and convexity of casing convex point on the rubbing response of rotor. Results showed that when the material of the casing convex point was comparatively hard, quasi-periodic motion of rotor could appear at lower speed. For a sharp convex point, the system response turned out to generate phenomenons of nonlinearities including periodic and quasi-periodic motions. When the clearance between rotor and stator was smaller, nonlinear vibration of the system would come into being in a region of high rotating speed.
