本文对应变式压力传感器用于滑动轴承油膜压力测量时的性能进行了多方面的试验。试验结果表明,应变式压力传感器具有容易满足的灵敏度。工作温度变化影响测量结果,但可采用合适的传感器参数和实验步骤来消除。动态实验和在轴承实验台上的实际测量都表明,传感器压力传递系统的弹性和阻尼可能对测量结果产生较大影响,在这种情况下,利用计算机对这些曲线进行修正获得了较好的效果。 In this paper, the strain gauge pressure sensor used in the oil film pressure measurement of the performance of a multi-faceted test. Test results show that the strain gauge pressure sensor has easy to meet the sensitivity. Changes in operating temperature affect the measurement but can be eliminated using suitable sensor parameters and experimental procedures. Both the dynamic experiments and the actual measurements on the bearing bench show that the elasticity and damping of the sensor pressure transfer system can have a significant effect on the measurement results. In this case, a good effect is obtained by using a computer to correct these curves .
