| 摘 要： | 根据气门-气门导管的润滑状况将润滑区域分为动力润滑区和弹流润滑区,两种润滑区域的计算采用了不同的网格;为了使数值计算快速收敛,对弹流区的雷诺方程进行了函数变换;根据气门的动力学、动力润滑和弹流润滑方程进行了数值求解,求得了气门相对于气门导管的平衡位置,并根据求得的最小油膜厚度和润滑区的有效粗糙度给出了气门-气门导管的润滑状态;最后根据气门-气门导管的润滑状态,提出了以接触区的最大接触应力作为限制气门-气门导管磨损的依据,并给出了气门-气门导管接触区应力的分布函数。 |
| 关 键 词： | 气门-气门导管 流体动力润滑 弹性流体润滑 接触应力 |

| Abstract: | The lubrication area is divided into the dynamic lubrication area and the elastic lubrication area basing on the lubrication status of valve-valve guide. The different grids are adopted in the two lubrication areas. Reynolds equation in elastic area is transformed by function in order to make convergence quickly. Through the iterative calculation of the valve dynamics, the dynamic lubrication and the elastic lubrication, the balance position relative to valve guide are gained. The lubrication status of valve-valve guide is estimated basing on the minimum oil film thickness and effective roughness. Basing on the lubrication status of valve-valve guide, the maximum stress of contact area used as the limit of the valve-valve guide abrasion is provided, and the Hertzian contact stress distribution function of valve-valve guide contact area is given. |
| Keywords: | Valve-valve guide Fluid dynamic lubrication Elastic liquid lubrication Contact stress |
