原文：Robust Machine Tool Thermal Error Modeling Through Thermal Mode Concept
Thermal errors are among the most significant contributors to machine tool errors.
Successful reduction in thermal errors has been realized through thermal error compensation techniques in the past few decades. The effectiveness of thermal error models directly determines the compensation results. Most of the current thermal error modeling methods are empirical and highly rely on the collected data under specific working conditions, neglecting the insight into the underlying mechanisms that result in thermal deformations. In this paper, an innovative temperature sensor placement scheme and thermal error modeling strategy are proposed based on the thermal mode concept. The modeling procedures for both position independent and position dependent thermal errors are illustrated through numerical simulation and experiments. Satisfactory results have been achieved in terms of model accuracy and robustness.

通过热模型概念建立机床热误差稳定性模型
热误差是机床误差的最主要因素，在过去的几十年中通过热误差补偿技术成功的降低了热误差，热误差模型的的有效性直接决定补偿的结果，目前的热误差建模方法大多是依靠经验和在特定工作条件下收集到到的数据，而忽略了对导致热变形的基本机构的分析研究，在本文中，根据热模型概念提出一种创新的温度传感器安装方案和热误差模型策略。该模型是通过数值模拟和实验对不同位置和不同位置的热误差进行说明，从而在模型精度和稳定性方面取得满意的结果。
