摘　　要：针对滚珠丝杠副温位移测量的要求,设计了滚珠丝杆副热伸长测量系统。介绍了试验台的硬件组成及数据采集流程。根据已有的设备制定了2种实验方案,对比分析后采用更符合实际工况的试验方案2,对汉江生产的某型号P3级精度丝杠的热伸长量进行了检测。运用最小二乘法对实验数据进行了处理分析,得出丝杠温升与伸长的关系。Based on the requirements of ball screw thermal elongation measurement,a precision ball screw detection system is designed. The hardware components and data acquisition processes are described. Two experimental programs are developed in accordance with existing equipment. According to the comparative analysis of the test programs,the second program which is more in line with the actual condition is conducted to detect the thermal elongation of the Han River products P3 level precision screw. The experimental data is analyzed to find out the relationship between the temperature and elongation.
