Automobile side sliding door pre-deformation design and analysis method

The invention discloses an automobile side sliding door pre-deformation design and analysis method. The method comprises the steps of firstly, establishing a finite element model of an automobile sidesliding door through 3D data, determining boundary conditions and a sealing strip rigidity curve, and analyzing and calculating deformation amounts of different positions of the side sliding door when a sealing rubber strip is extruded by the side sliding door after the side sliding door is closed; and then reversely superposing the deformation value into an initial side sliding door model for pre-deformation treatment to finally obtain the pre-deformation of the automobile side sliding door. According to the deformation processing method, the deformation degree of the vehicle door can be effectively reduced when the vehicle door is closed, so that the matching degree of the vehicle door frame and the vehicle body outline is improved, the sealing performance, the waterproofness and the noise reduction capacity of
