针对某型号总装过程中,两球面舱体装配之后形成的密闭空间曲面间隙测量,设计了一套基于直线位移传感器的测量系统,采用电阻值变化反映位移的方法,对该空间间隙进行精密测量。整个测量系统包括数据采集、存储和处理子系统。为了保证系统的精度,设计了标定系统。测量实验表明,整个测试系统能够对两球面舱体间隙进行测量,测量精度可达0.005mm。 |

Abstract: |
A system based on linear displacement sensor is designed for the distance measurement between two hemispherical surfaces. The system consists of data collecting, storage and processing subsystems. A calibration subsystem is designed for accuracy assurance. The results show that the measure system can correctly get the distance between two hemispherical surfaces, and the accuracy is up to 0.005mm. |
