内燃机轴承模拟分析和试验方法的研究进展

Advancements of simulative analysis and test method of bearings for I. C. Engine

随着发动机性能、功率和耐久性的不断提高 ,对轴承的负荷和使用寿命提出了更高的要求 .为了适应这些新要求 ,各国研究人员进行了多方面的探索 .目前研究重点集中在轴承性能的模拟分析和试验方法、负荷等方面 ,本文对这些成果做了简要介绍 .

With the continuous progress of performance, power and durability of internal combustion engine, much higher requirement was needed for the load and fatigue life of bearing. To fulfill these requirements, much more efforts are being implemented by scholars and engineers from all over the world.Recent emphasis of research is concentrated on the simulation analysis method, experimental method, load, wear and so on .On the basis of the above mentioned, larger load and longer fatigue life bearing could be expected in initial design stage, thus they are beneficial to improve performance power efficiency and lower fuel consumption and are briefly preseted in this paper..
