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.

通過熱模型概念建立機(jī)床熱誤差穩(wěn)定性模型
熱誤差是機(jī)床誤差的最主要因素，在過去的幾十年中通過熱誤差補(bǔ)償技術(shù)成功的降低了熱誤差，熱誤差模型的的有效性直接決定補(bǔ)償?shù)慕Y(jié)果，目前的熱誤差建模方法大多是依靠經(jīng)驗(yàn)和在特定工作條件下收集到到的數(shù)據(jù)，而忽略了對導(dǎo)致熱變形的基本機(jī)構(gòu)的分析研究，在本文中，根據(jù)熱模型概念提出一種創(chuàng)新的溫度傳感器安裝方案和熱誤差模型策略。該模型是通過數(shù)值模擬和實(shí)驗(yàn)對不同位置和不同位置的熱誤差進(jìn)行說明，從而在模型精度和穩(wěn)定性方面取得滿意的結(jié)果。
