Abstract
The invention discloses an integrated forming method of an automobile front bumper beam and a front bumper beam. The integrated forming method comprises the steps of load transmission and target performance decomposition, structural design and simulation optimization, precision casting integrated forming and simulation and experiment combined performance analysis. According to the front bumper beam, a plurality of parts such as the bumper beam body, the energy absorption box, the vehicle body mounting plate and the tow hook nut are integrated into a whole by adopting a precision casting integrated forming technology. Compared with a traditional process, the integrated forming method of the automobile front bumper beam has the advantages of being high in integrality, simple in process, lowin comprehensive cost and the like while the light weight of the assembly and the improvement of the overall performance are greatly achieved. According to the integrated design method, the comprehensive performance of the front bumper beam assembly is improved while integrated forming and structural light weight are achieved.
Description
technical field [0001] The invention relates to a lightweight design method of an automobile structure in the field of automobiles, in particular to an integrated molding method of a front bumper beam of an automobile and the front bumper beam. Background technique [0002] Facing the increasingly severe environmental and energy crisis, lightweight design has become an important way to achieve effective energy saving and emission reduction for automobiles. Relevant studies have shown that for every 10% reduction in the weight of a car, the fuel consumption of fuel vehicles can be reduced by 6% to 8%, and the relative pollution emissions will be reduced by 10%; the energy saving rate of electric vehicles can reach 4 to 5%. Vehicle battery costs will also be reduced. Therefore, the reduction of vehicle mass is of great significance to both traditional fuel vehicles and new energy vehicles. The production of lightweight car bodies is inseparable from advanced manufacturing te...
