针对某自卸车转向节结构早期失效，存在断裂可能性等问题，参照车辆行驶状况和汽车设计手册，详细分析转向节在紧急制动、侧滑(向左侧滑)和越过不平路面3种工况下的受力情况。运用UG软件和ANSYS软件，建立了3工况转向节有限元模型，分析3种工况下的转向节应力应变分布规律。通过寻找最大应力处和最大位移处，找出了转向节在各种工况下易损坏部位，并探讨了其易损坏的具体原因。研究结果表明，该转向节最大应力小于材料许用应力，符合汽车设计手册中的安全条件，为转向节的设计提供理论指导。

According to the load states of wheels’ movement and the vehicle design manual, force conditions of the steering knuckle under three dangerous situations are studied in details, and the formulas of force and torque are given respectively. Then its solid model created by UG software is imported into ANSYS and the static strength analysis is used to discuss stress and deformation of the steering knuckle under three dangerous situations, and provided a theoretical guidance for the design of the steering knuckle.
