摘要
以一款鹅颈集装箱半挂车车架为研究对象,采用理论分析和仿真手段相结合,对车架结构强度和刚度进行验证。利用OptiStruct分析工具对车架在满载弯曲工况、满载转弯工况以及满载制动工况下进行有限元分析,结果表明:三种实际工况下,车架的高应力区域基本相同,且主要集中在纵梁阶梯连接处和牵引销连接处,高应力区域主要出现在焊接处;变形最大位置主要发生牵引销与第一排板簧之间。
Taking a gooseneck container semi-trailer frame as the research object, the combination of theoretical analysis and simulation means to verify the strength and rigidity of the frame structure. Finite element analysis was carried out for the frame under full load bending, full load turning and full load braking conditions by using OptiStruct. The results show that under the three actual working conditions, the high stress area of the frame are basically the same,and mainly concentrating in the stair of longitudinal step joint and traction pin joint, the high stress area mainly appears in the welding place;The maximum position of deformation mainly occurs between the traction pin and the first platelet spring.
