| 摘要: |
| 在任何严峻条件下现代机械运行中综合性能的迫切需求促进了许多先进表面工程技术的迅速发展。因而，设计者在结构设计时将有许多表面工程技术可以选择。但是，怎样为一种特定的应用选择一种最优化的表面工程方法对设计者来说又是一种挑战。为了这个目标，在现代多层表面接触理论的基础上建立起一种接触力学模型，考虑到了多层结构、真实表面粗糙度和摩擦影响。这种力学模型可以成功地预测表面工程结构的性能。文中首先回顾了赫兹接触理论的发展过程，然后讨论了伯明翰多层真实粗糙表面接触力学模型，并用实例示范了一系列关于动载荷下表面工程结构设计的主要步骤。 |

| Abstract: |
| The ever-increasing demands for combined properties in modem machinery operating under ever more severe conditions have been the driver for the rapid developments of many advanced surface engineering technologies. Designers thus have many surface engineering technologies to select from in the design of components. However, it also presents challenges to designers to select an optimal surface engineering process for a specific application. To this end, a contact mechanics model has been developed based on modem theories of multi-layered surface contact, taking into account the multi-layered structure, real surface roughness and friction effects. With this model, the performance of surface engineered components can be successfully predicted. In this paper, the development of Hertz contact theory is first reviewed, the Birmingham multilayered real rough surface contact mechanical model is discussed and a number of major steps towards designing dynamically loaded surface engineered components are demonstrated by case studies |
