The invention relates to the technical field of spherical hinge structure design, and discloses a design method of an automobile spherical hinge, which comprises the following steps: simulating the maximum load of the automobile spherical hinge through software; according to a formula # imgabs0 # # imgabs1 #, a ball head with the minimum ball head diameter D'is obtained; an assembly digital model of the automobile suspension system is built through software, and the minimum swing angle beta'of the automobile spherical hinge is obtained; according to a formula L'chord length = D 'ball head * sin beta', the minimum chord length L'chord length can be obtained; and sigma j'is obtained according to the formula # imgabs2 and the strength calculation formula in the step 2, optimization design is carried out on the ball head with the minimum ball head diameter D ', and the ball head with the optimal ball head diameter D is obtained. By the adoption of the design method, the maximum load and strength of the automobile spherical hinge can be considered in the initial design stage of the automobile spherical hinge, the diameter of the ball head can be accurately designed, and the problems of breakage, abnormal abrasion and the like after sale are effectively avoided.

    本发明涉及球铰结构设计技术领域,公开了一种汽车球铰的设计方法,包括:通过软件模拟仿真汽车球铰的最大载荷;根据公式#imgabs0##imgabs1#求得最小的球头直径D′球头;通过软件搭建汽车悬架系统的装配数模,得到汽车球铰的最小摆动角度β′;根据公式L′弦长=D′球头·sinβ′,即可求得最小弦长L′弦长;根据公式#imgabs2#和步骤2中的强度计算公式得出σj′,将最小的球头直径D′球头开展优化设计,得到最优的球头直径D球头。采用本发明的设计方法,能够在汽车球铰的设计初期就考虑到汽车球铰的最大载荷和强度,即可精准设计球头直径,有效避免售后出现断裂、异常磨损等问题。
