摘要：为了分析某款车型转向节在穿过不平路面、紧急制动、最小转向半径且不侧滑3种典型危险工况下是否会出现静力破坏现象，建立了转向节有限元模型，对转向节的3种典型危险工况进行了力学分析，并基于Nastran对此转向节在3种典型危险工况及组合工况的静强度进行了有限元分析。有限元分析结果表明该转向节可以满足静强度要求。

Abstract: Aiming at analyzing the stress circumstances under typical dangerous work conditions of this vehicle types steering knuckle, such as uneven road, emergent braking and minimal turning radius without sideslip, the finite element model was made. The stresses of steering knuckle under the three typical dangerous work conditions were analyzed, the static strength of the steering knuckle under the three typical dangerous work conditions and combination conditions was analyzed by using a finite element method based on Nastran. The results show that this steering knuckle can satisfy the static strength requirements.
Key words: steering knuckle; finite element analysis; stress; Nastran
