【摘要】 在用点热源温度场积分法求解点接触干摩擦或混合润滑的温度场时,原有的数学模型未能考虑到可能的两固体表面之间的传热,因而会造成热流分配系数出现不合理的结果。为此对该数学模型进行了修正,计及了两固体表面之间的热传导,提出了与之相适应的算法,并采用算例结果进行了验证分析。更多还原

【Abstract】 In the thermal analysis of dry contact and mixed lubrication in point contacts, the original point heat source integration method does not consider the possible heat conduction between frictional surfaces, which will result in the irrational heat partition coefficients. The method is revised by considering the heat conduction between two frictional surfaces and new algorithm is put forward to the new model in this paper. Numerical sample validates the model and algorithm.更多还原
