摘要
基于JFO理论 (Jakobsson,Floberg ,Olsson)提出的质量守恒边界条件 ,对二维动载滑动轴承的线性稳定性在考虑空穴因素影响的条件下进行分析研究 ,建立相应的模型及方程 ,进而求得动力特性系数 ,以便进一步更准确的考察其稳定性。最后 ,对一个 36 0°的普通圆柱动载径向轴承进行实例计算 ,计算结果显示和实验测量数据吻合的较为一致。
Based on JFO theory, the two-dimensional linear stability analysis was presented considering the effect of cavitation for a plain cylindrical journal bearing, a universal Reynolds equation was constructed including both full film region and cavitation region, and linearized stiffness and damping coefficients were obtained from the equation. A 360° plain cylindrical journal bearing was taken as an example to analyze its stability. The results show good agreement between theoretical and experimental results.
