Problems solved by technology
However, the added longitudinal beam reinforcement plate and suspension reinforcement plate are separate independent structures, and there is no supporting structure in the Y direction or Z direction inside the longitudinal beam, which makes the bending resistance of the longitudinal beam poor and the structural defect of the longitudinal beam In the process of collision, it is easy to deform in advance, and the deformation mode and deformation sequence of the longitudinal beam cannot be effectively controlled

Description
technical field [0001] The invention relates to a vehicle body structure, in particular to an automobile longitudinal beam reinforcement and an automobile. Background technique [0002] In the NCAP (New Car Assessment Program, new car crash test) evaluation test, the vehicle hits a barrier (deformable or rigid wall) at a certain speed to simulate the actual situation of a traffic accident. NCAP uses the damage value of the dummy placed in the collision vehicle to evaluate the safety performance of a new car. The lower the damage of the dummy, the higher the safety performance of the vehicle. During the collision process, part of the initial kinetic energy of the collision is absorbed by the deformation of the key components of the front cabin, and the remaining energy is transmitted to the passenger compartment, which is absorbed by the deformation of the passenger compartment and the occupants in the vehicle. The greater the energy transmitted to the passenger compartment,...
