摘　　要：从理论上分析了机床主轴温度场与热变形的动态特性,证明了机床主轴上最佳温度测点的存在,并通过实验加以论证。采用黄金分割法对主轴最佳温度测点的位置进行优化,并采用最佳温度测点处的温度建立线性函数,精确预报主轴的热伸长量。The discrepancy between the temperature field and the thermal deformation of the spindle of machine tool is analyzed both in theory and experiment.The existence of the optimal temperature sensor placement in the spindle is proved.Its location is optimized by the gold section method.At this optimum location there is an approximate linear relation with synchronization between the thermal expansion and the temperature of spindle.[
