| 10. | The fem results indicated that as to the rough surfaces in sliding contact , the value of the contact pressure was very high which coursed a high value of the heat flow rate , meanwhile the sliding time was not enough for the frictional heat to transfer , thus the highest value of the body temperature occurred just on the sliding surfaces , which possessed a sharp thermal gradient in direction perpendicular to the sliding surface . so the great thermal stress was caused just by the sharp gradient and the thermal elastic distortion with which the contact pressure changed occurred simultaneously , thus this change of the contact pressure would affect the temperature distribution in return 对于相对滑动的粗糙表面,因实际接触面积小而导致接触压力很大,这样使得热流密度会很大,同时由于滑动时间很短,热来不及传导,最高温度发生在摩擦表面,在垂直于摩擦面的方向有很大的温度梯度,使得热应力很大,且最大应力发生在表面,同时产生热弹性变形,这种变形使得接触区域内的压力分布发生变化,这种变化又反过来影响了接触区域的温度分布。 |
