摘要：

高速压力机曲轴热态有限元模型的准确建立对高速压力机在虚拟环境下的理论研究有着重要的意义。以有限元方法为基础，建立基于接触热阻这一边界条件的曲轴热模型，并进行温度场和热变形分析。通过电涡流传感器对曲轴实际的热变形量进行实验测量，实验结果表明，考虑接触热阻的有限元模型分析结果更接近实际工况，理论分析误差由14.46%降低到2.37%。因此考虑接触热阻这一边界条件的主轴热态有限元模型更能准确反映高速压力机曲轴的热特性，有限元模型更加合理。

Accurate establishing of thermal model for high-speed press spindle is of great importance to press theoretical analysis in the virtual environment. Based on finite element analysis, thermal model of crankshaft was built based on boundary condition of thermal contact resistance, while distribution of temperature field and thermal deformation were analyzed. The actual thermal deformation of crankshaft was measured through eddy-current sensor. It is found that new thermal model considering the thermal contact resistance is closer to real thermal condition of crankshaft, which reduces the error to 2.37% from 14.46%. Therefore thermal model of crankshaft considering the thermal contact resistance responds the thermal characteristics of high speed press crankshaft much more accurately, which is much more reasonable.
