frictional heating meaning in English
摩擦加热
摩擦生热
Examples
- This depends on the estimation of the temperatures generated by frictional heat .
它取决于摩擦热所引起的温度估算。 - The result shows that it is mainly caused by the martensite with high hardness produced after rail absorbing frictional heat
断裂的主要原因是钢轨在吸收摩擦热后产生了高硬度的马氏体。 - The biggest fuel savings achieved by a full hybrid vehicle derives from regenerative braking , a technology that captures as electrical power much of the energy normally lost as frictional heat
高量级混合车最大的省油关键来自再生制动（煞车）技术，这种技术可捕集摩擦热（通常几乎散失掉的能量）并转变成电力。 - The effect of the variation of temperature and contact pressure of the sliding contact surfaces with frictional heating on each other , particularly the relationship of the applied pressure and the contact pressure and the effect of the separate variation of some parameters on the simulation results were taken account into in the course of numerical simulation
在数值计算过程中，着重考虑了温度变化与接触区域压力变化的耦合问题，接触压力与外加压力的关系，以及分别改变一些参数对结果的影响。 - 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。
