大尺寸、高精度测量中温度误差的修正方法及其比较

Temperature Error Correction Methods and Comparison in the Large-size and High-precision Measurements

为减少大尺寸检测中温度误差引起的测量误差,介绍修正测量误差的两种方法:公式计算和恒温方法。在恒温方法中,介绍如何利用MATLAB和Pro/M软件模拟来确定工件的恒温时间(以动态温度显示),以消除温度变化对测量结果的影响。并对公式计算和软件仿真两种修正方法的效果进行比较。

To reduce the measurement error caused by temperature error in large-size and high-precision measurements, two measurement error correction methods were described ： formula method and constant-temperature method. In the constant-temperature method, how to use the MATLAB and Pro/M software simulation to determine the constant temperature time were introduced which was displayed as dynamic temperature, to eliminate the impact of temperature changes on the measurement results. The effectivenesses of the formula method and the simulation method were compared.
