【摘要】 系统地阐述了发动机缸套活塞组瞬态摩擦力的测量方法。在对浮动缸套法的原理进行仔细的研究及对其难点进行详细的分析之后,一种改进的具有某些显著优点的测量装置被开发出来。并利用这个装置,测出了各种工况下缸套活塞组的摩擦力的变化。更多还原

【Abstract】 This paper introduces systematically the method for measuring the instantaneous friction force of cylinder liner-piston pair in the engine. After the principle of floating cylinder liner method is carefully studied and its difficult point is analyzed in detail,an improved measuring device with some marked advantages is developed. Some changes of friction force of cylinder liner-piston pair are measured under various working conditiions by using this device.更多还原
