报告模板主要内容论文摘要:

Lওubricated concentrated contacts are common in engineering applications, mostly between "hard" materials (steel) as in rolling bearings, cam-followers, and gears, but also between a hard and a soft part as in the case of a steel and an elastomeric seal. In recent decades, soft materials are increasingly used in mechanical engineering, in aviation industry, and in various processes in physics, and biomechanics, due to advantages such as light weight, good recyclability, and controllable design-performance capability. For “hard” materials, the deformation of the contacting elements is predominantly elastic. The understanding of the physical mechanisms governing the lubrication film formation and the associated pressure generation has reached a very high level of predictability. However, soft materials exhibit viscoelastic behavior in contacts, and, in spite of the excellent work that has been done regarding the elastomeric seal contacts, the current understanding of the effect of solid viscoelasticity on the lubrication of soft contacts, particularly for point contacts, is less advanced than the understanding of the purely elastic contacts. This limits the design and performance optimization of the related tribological contacts and✱systems. In this presentation fundamental aspects of the modeling and efficient numerical simulation of viscoelastic point contact problems are introduced.
