| 摘 要： | 针对影响机床加工热误差建模的机床温度场分布问题，借用灰色系统理论的关联度分析方法。对热传感器在机床上的优化布点进行了研究，从原先的16个温度测点减少到仅使用其中的4个关键温度进行热误差建模，从而可以较简便的分析所研究机床的热误差，提高了热误差建模的鲁棒性。

| Abstract: | Aimed at the influence of temperature field distribution of machine tool on the thermal error medeling, the optimizing points of thermal sensors using the grey correlation model of grey system theory was studied. The thermal error model was established through only four key temperature measuring points from the original 16 points, which can analyze the thermal error of machine tool easily and increase the robustness of thermal error modeling. |
