The invention relates to the field of automobile assembly, in particular to an automobile chassis integral assembling method. The automobile chassis integral assembling method comprises the followingsteps: S1, calculating an assembling success rate by adopting a plane dimension chain model based on a deviation parameter, adjusting the deviation parameter according to the assembling success rate until the deviation parameter meets a specified success rate, and then entering the step S2; and S2, assembling the automobile chassis according to the deviation parameter. According to the automobilechassis integral assembling method, various important deviations are comprehensively considered based on an integral assembling scheme of multi-stage control, a mathematical model of the integral assembling success rate of the chassis based on a plane dimension chain is established, optimal dimension tolerance distribution is achieved, and therefore manufacturing and installing links can be quantitatively optimized, and the assembling success rate is increased.

    本发明涉及汽车装配领域,更具体的说,涉及一种汽车底盘整体合装方法。本发明提出的一种汽车底盘整体合装方法,包括以下步骤:S1、基于偏差参数,采用平面尺寸链模型计算合装成功率,根据合装成功率调整偏差参数直至满足指定成功率后进入步骤S2;S2、根据偏差参数对汽车底盘进行合装。本发明提出的汽车底盘整体合装方法,基于多级控制的整体合装方案,综合考虑了各重要偏差,建立基于平面尺寸链的底盘整体合装成功率的数学模型,实现最优尺寸公差分配,从而可定量优化制造安装环节,提高合装成功率。
