Using four evaluation criteria of contact peak, the thermal contact resistances of machining surfaces are calculated.

分别采用四种接触峰的评定标准，对实际机械加工表面的接触热阻进行了计算。

But the peak of contact pressure between rolls forms when the intermediate roll shifts, which leads local wear of rolls and quality defects of strip.

但由于中间辊轴向窜动后，在工作辊与中间辊、中间辊与支撑辊间形成接触压力峰值，导致轧辊局部磨损及带材表面质量问题。

The results show that the peak of contact pressure moves forward and the different value of internal energy and damage dissipation energy becomes bigger with the increasing of impact energy.

结果表明：随着冲击能量的增大，接触力峰值前移，且冲击后板吸收能量与损伤散逸能的差值变大。
