摘要
对轴承不对中的故障转子系统进行了仿真分析和实验研究,得到了系统的振动特性;对比分析了健康转子与存在不同不对中量的故障转子间振动特性的差异。结果表明:当转速到达1/2倍一阶临界转速时,故障转子会发生2倍频共振;转子转速接近一阶临界转速时,转子的基频响应会很大,但系统的不对中振动特征并不明显。
The vibration characteristics of the faulty rotor system with bearing misalignment were obtained based on the simulation analysis and experimental research. The vibration characteristics between healthy rotor and faulty rotor with different misalignment values were compared and analyzed. The results showthat the second harmonic resonance will happen when the rotor speed is close to half of the 1stcritical speed,whereas the first harmonic response is high and the vibration characteristics of the system with misalignment is not obvious when the rotor speed is close to the 1stcritical speed.
