摘要：在目前的三维逆热传导问题中估算了切削刀具切削刃上的表面热通量。根据红外热成像模拟测量的工具表面温度分布，利用最速下降法 (SDM) 和通用商业代码 CFX4.4 的逆算法在本研究中成功应用。采用两种不同的工具形状来说明不同测量误差下未知热通量反演的有效性。数值模拟结果表明，利用本发明的反演算法可以获得可靠的热通量估计值。
ABSTRACT The surface heat fluxes on the cutting edges of cutting tools are estimated in the present three-dimensional inverse heat conduction problem. The inverse algorithm utilizing the steepest descent method (SDM) and a general-purpose commercial code, CFX4.4, are applied successfully in this study in accordance with simulated measured temperature distributions on tool surfaces by infrared thermography. Two different tool shapes are used to illustrate the validity of inverse determination of the unknown heat fluxes with different measurement errors. Results of the numerical simulation show that reliable estimated heat fluxes can be obtained by using the present inverse algorithm.
