螺纹计算中有限元与经典力学的联合应用

The United Application of the Finite Element Method and Classical Mechanics to Calculating Bolt’s Intensity

针对某受力螺栓,先建立整个结构的有限元模型,用有限元方法计算出螺栓所受的外力,然后用该计算结果和螺栓的已知条件,通过经典力学对其强度进行校核。通过有限元与经典力学的联合应用,得到了该螺栓较为精确的强度校核结果。

Aiming at some bolt which bears force, this paper presents that the finite element model of bolt has been constructed, the force which the bolt bears has been calculated,and then with this force result and other conditions known, the bolt＇s intensity has been proofread through classical mechanics. More accurate result about intensity proofread has been gotten through the united application of the Finite Element Method and classical mechanics.
