查询词典 bolt

Combined with CAD software development of grids,the design method of bolt-sphere joint is put forward based on geometry restriction and intensity restriction. The geomitry dimension of each component is determined firstly based on bolt diameter and contexture, then, maximal pull and stress of diversitied bolt are given after intensity restriction of all components is taken into acount.
