本文分析了Ruston和Hornsby VEB柴油机连杆轴承圆截面和非圆截面的动态特性。空化的影响被认为是通过使用空化算法，它模仿JFO边界条件。质量惯性的影响占通过求解耦合的非线性运动方程。所考虑的轴颈轮廓是圆形、椭圆形、半椭圆形和三叶外摆线。一个完整的负载周期的预测轴颈轨迹和其他性能参数，提出了所有的不圆的轮廓，并与圆形轴承的预测进行了比较。参考文献18篇。
In this paper, the dynamic performance of the Ruston and Hornsby VEB diesel engine connecting-rod bearing with circular and out-of-round profiles is analyzed. The effect of cavitation is considered by using a cavitation algorithm, which mimics JFO boundary conditions. The effect of mass inertia is accounted for by solving coupled nonlinear equations of motion. The journal profiles considered are circular, elliptical, semi-elliptical, and three lobe epicycloid. The predicted journal trajectory and other performance parameters for one complete load cycle are presented for all of the out-of-round profiles and are also compared with the predictions for the circular bearing. 18 refs.
