使用 Jakobsson、Floberg 和 Olsson 空化边界条件的质量守恒算法（Elrod 算法）已用于分析曲轴轴承。考虑典型汽车发动机的主轴承和连杆轴承。给出了一些稳态结果样本。针对实际发动机负载，解决了反问题（给定负载，找到轴颈轨道）。与基于雷诺边界条件的非保守算法进行了比较。两种算法之间观察到空化区和油流的显着差异。在所有情况下，根据 Elrod 算法，流入轴承的油流与流出轴承的油流相匹配。于 1989 年 5 月 1-4 日在佐治亚州亚特兰大举行的第 44 届年会上提出
A mass conserving algorithm (Elrod algorithm) which uses the Jakobsson, Floberg, and Olsson cavitation boundary conditions has been implemented to analyze crankshaft bearings. The main and connecting rod bearings of a typical automotive engine are considered. Some sample steady-state results are presented. The inverse problem (given the load, find the journal orbit) is solved for real engine loads. Comparisons are made with a non-conservative algorithm based on the Reynolds boundary condition. Significant differences in the cavitation zones and oil flows are observed between the two algorithms. In all cases, the oil flow into the bearing is found to match the oil flow out of the bearing for the Elrod algorithm. Presented at the 44th Annual Meeting in Atlanta, Georgia May 1–4, 1989
