The problem discussed in this paper concerns a finite elements analysis of a flange destined to close high power compressors or engine cylinders. This type of flange is overhanging bolted and solicits the screw or the bolt in flexion. It is necessary to know the extent of this flexion as well as the characteristics of stiffness of the connection that is equally solicited in fatigue. The goal is to realize a simple analytic model, usable in engineering. 相似文献

With the help of the results obtained from test rig experiments and a comparison with the original system, it is demonstrated to what extent the traction-creep relationships of wheel-rail contact are influenced by surface contamination, oxide layers, roughness, plastic deformations and the preferred crystal orientations (textures) they cause, and dynamic variations in vertical load. 相似文献
