汽车低速碰撞轻量化保险杠安装结构优化设计

Optimal Design of Lightweight Bumper Mounting Structure in Low Speed Collision

汽车的低速碰撞性能是考量汽车安全性和维修经济性的重要指标。汽车的前后保险杠作为车体结构的主要防护件,在发生低速碰撞时,可以吸收车体碰撞的能量,缓和碰撞对车身的冲击,降低碰撞对车体结构的损坏程度。因此,针对汽车保险杠结构的优化设计一直是汽车生产制造的研究重点。在汽车轻量化的大趋势下,优化保险杠安装结构设计的同时,使用轻质制造材料,不仅可以提高汽车的低速碰撞的安全性,还可以提高车辆的燃油经济性。

Low speed collision performance is an important index to consider vehicle safety and maintenance economy.As the main protective parts of the car body structure,the front and rear bumpers can absorb the energy of the car body collision,mitigate the impact of the collision on the car body and reduce the damage to the car body structure.Therefore,the optimization design of automobile bumper structure has always been the research focus of automobile production and manufacturing.Under the general trend of vehicle lightweight,optimizing the design of bumper mounting structure and using lightweight manufacturing materials can not only improve the safety of vehicle low-speed collision,but also improve the fuel economy of vehicle.
