Abstract: This paper studies the optimization of the width of the whole vehicle at the multi purpose vehicles sliding door. The width of the whole vehicle is determined by the layout of the upper body and the layout of the lower body. The influence of the layout of the lower body on the width of the whole vehicle is mainly the size of the tire, the size of the engine and the size of the suspension. When the tire and the engine are fixed, the width of the whole vehicle is adjusted by fine-tuning the suspension size. The influence of the layout of the upper body on the width of the whole vehicle is mainly the size of the riding space, When the riding space is certain, the key point of vehicle width optimization is the sliding door hinge track layout. The sliding door MPV vehicle width optimizes the suspension arm length and sliding door hinge track layout through ADMAS simulation.
