The invention discloses a steering wheel misalignment problem optimization method, system and equipment and a medium, mainly relates to the technical field of steering wheels, and is used for solving the problem that an existing scheme does not relate to an optimization processing scheme of data of a plate spring, a knuckle arm and the like and cannot optimize the steering wheel misalignment problem in the directions of the plate spring, the knuckle arm and the like. Comprising the following steps: updating a vehicle front suspension three-dimensional digital model in kinetic analysis software; basic information of the entity plate spring is obtained, and then the mapping relation between the load and the rigidity corresponding to the plate spring in the dynamic analysis software is updated; acquiring the variation range of the position of the required key hard point; adjusting the three-dimensional digital model of the vehicle front suspension based on the variation range, and applying a load from no load to preset full load to the plate spring through the plate spring mounting point and the central point of a front spring eye of the plate spring, so as to call a preset simulation program to obtain the steering interference amount corresponding to the current three-dimensional digital model of the vehicle front suspension in real time; and the preset key hard point position corresponding to the minimum steering interference amount is determined.

    本申请公开了一种转向盘不正问题优化方法、系统、设备及介质,主要涉及转向盘技术领域,用以解决现有方案并不涉及板簧和节臂等数据的优化处理方案,无法从板簧和转向节臂等方向进行转向盘不正问题优化的问题。包括:更新动力学分析软件中的车辆前悬架三维数字模型;获取实体板簧基础信息,进而更新动力学分析软件中板簧对应的载荷与刚度之间的映射关系;获取所需的关键硬点位置的变动范围;基于变动范围调整车辆前悬架三维数字模型,以及通过板簧安装点和板簧前卷耳中心点向板簧施加从空载到预设满载的载荷,进而调用预设模拟程序实时获得当前车辆前悬架三维数字模型对应的转向干涉量,直至确定最小转向干涉量对应的预设关键硬点位置。
