用热源叠加原理研究圆孔车削温度场

Research of hole workpiece turning temperature field based on the heat source adding principle

基于移动热源法及热源叠加原理,对圆孔车削温度场进行研究。提出局部温度场和总温度场的分析方法,推导出瞬时圆环热源温度场的描述方程,为圆孔工件的工程实际热问题提供了理论计算方法。

The temperature field of hole workpiece turning was researched based on the moving heat source and heat source adding principle. The analysis method of partial temperature field and whole temperature field was put forward and the integral equation of hole workpiece temperature field on instantaneous circle heat source was deduced. An effective way is thus available to solve such engineering thermal problems as the calculation of the hole workpiece temperature field.
