摘　　要：为了识别多支承轴系中的轴承载荷、分析其振动特性和研究动力学行为,设计了四支承轴承转子试验台的测试系统。通过一种测力传感器实现轴承动态载荷的直接测量,采用位移、加速度及扭矩传感器分别获取轴系的轴心轨迹、振动和扭矩等信号,针对实际调试过程中产生的噪声信号采取了有效的抗干扰措施。试验结果表明,测试系统可以对整个轴系进行多参数在线监测,所采集的数据真实可信。Aiming at identifying the bearing load in the muhi-support shafting, analyzing vibration characteristic, and researching dynamic behaviors, the test system of the four-support rotor-bearing test-bed was designed. It realized direct measurement for bearing dynamic loads using the load-sensor, obtained axes track, vibration and torque signal by displacement ,acceleration and torque sensor. The effective anti-jamming measures were taken to eliminate the noise signal generated in the actual debugging process. The experiment results show that the test system can multi-parameter online monitor the shafting, and the data are authentic ＆ dependable.
