Finite Element Method Analysis And Experimental Research Of Spherical Bearing Considering Contact Surface Character

Spherical bearing is a kind of bearing adopted widely on the city flyover and road bridge. Certain achievement has been get in theory and the experiment study on spherical bearings. Main work of this paper is to study the impact of contact surface character over finite element method analysis result of bearing and how rationally to ascertain the contact surface character parameter.Research contents of this paper are: firstly, to analyze the impact of every contact surface character parameter over finite element method analysis results of bearing; secondly, to analyze and compare finite element method analysis result with experiment result of two kinds of contact surface ,so as to testify the rationality of the contact surface character parameter; finally, to study how to reasonably ascertain the contact surface character parameter during the period of structure overall analysis, and to design bearing on the basis of structure overall analysis...
