This paper introduces the durability analysis of open and close parts of car body
Auto opening and closing parts are complex parts in auto body, which involves parts stamping, wrapping and welding, parts assembly, assembly and other processes. They are strict in size matching and process technology. Car opening and closing parts mainly include four car doors and two covers (four doors, engine cover, trunk cover and some MPV special sliding door, etc.) structure and metal structural parts. The main job of the auto opening and closing parts engineer: responsible for the design and release of the structure and parts of the four doors and two covers of the car, and drawing and improving the engineering drawings of the body and parts; According to the section completed four doors and two cover sheet metal design, and motion simulation analysis; Develop and implement the work plan for quality improvement, technology upgrade and cost reduction of body and parts. Auto opening and closing parts are the key moving parts of the body, its flexibility, robustness, sealing and other shortcomings are easy to expose, have a serious impact on the quality of automotive products. Therefore, manufacturers attach great importance to the manufacturing of opening and closing parts. The quality of automobile opening and closing parts actually directly reflects the level of manufacturing technology of manufacturers
