饰性斜拉拱桥设计关键问题探讨

随着社会的不断发展进步,人们对桥梁设计美观性的要求越来越高。许多桥梁以简支梁板桥为基本体系,新增装饰性结构形成景观桥梁,以满足人们的观赏性。通过对一座装饰性斜拉拱桥设计进行总结,为今后同类型工程设计提供参考。

Discussion on Key Problems in Design of Decorative Cable-stayed Arch Bridge

The steel ball bearing is more and more widely used in the engineering projects because of its good turning property and other advantages. In order to further improve the performances of steel ball bearing, to develop the potential of steel ball bearing and to widen its application prospect, the new high-performance friction pair material is required to use. The system composed of two objects not only directly contacting, but also producing the relative frictional motion is named as the friction pair. In the steel ball bearing, the friction pair is one of the key component parts. The friction performance and mechanical property of its materials can determine the advantages and disadvantages of the whole performance of steel ball bearing in a certain extent. The application prospect and key performance parameters of friction pair material at home and abroad are mainly introduced. And the similarities and differences of the methods of index detection in the different countries are also introduced.
