Abstract：

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.
