内燃机的研制经验表明:保证曲轴轴承的可靠工作,乃是发动机机械部分设计工作的主要任务之一。因此,计算评价这类轴承工作能力的方法和手段,是正在研制的内燃机自动化设计系统的一个重要组成部分。计算曲轴与非稳定曲轴轴承的相对运动时,人们所研究的是在指向曲轴中心的外力总矢量和使其平衡的机油流体动力反作用力的作用下,曲轴的瞬时平衡状态(图1)。如所周 Experience from the research and development of internal combustion engines shows that ensuring the reliable operation of crankshaft bearings is one of the major tasks in engine mechanical part design. Therefore, the method of calculating and evaluating the working ability of such bearings is an important part of the developing system of internal combustion engine automation design. When calculating the relative motion between a crankshaft and a non-steady crankshaft bearing, one has studied the instantaneous equilibrium state of the crankshaft (Figure 1) under the influence of the total vector of external forces directed to the center of the crankshaft and the hydrodynamic reaction force balanced by it.
