Excuse me, does the modification and repair of the automobile beam head have an impact on the overall structure of the automobile?
The impact of the repair is that the original morphological parameters cannot be restored, so there will be some minor problems such as abnormal noise and direction deviation of the vehicle.

The longitudinal beam absorbs collision energy through crushing deformation and bending deformation, and the front longitudinal beam bears 60% of the total collision energy. Although the rear longitudinal beam needs to bear less energy-absorbing pressure than the front longitudinal beam, it is still the main energy-absorbing force in the rear-end collision. Therefore, if the front and rear longitudinal beams are injured in the accident, the protective effect of these two beams on the cockpit will be greatly reduced in the future driving process.

Advantages of cars with crossbeams

1. The flexible rubber pad not only plays the role of cushioning and shock absorption for tires and suspension systems, but also plays the role of auxiliary cushioning, properly absorbs the torsional deformation of the frame and reduces noise, which not only prolongs the service life of the car body but also improves the ride comfort, and is widely used in limousines and some intermediate cars.

2. The chassis and the car body can be assembled separately and then assembled together, which can simplify the assembly process and facilitate the organization of specialization and cooperation.

3. The frame is used as the foundation of the whole vehicle, which is convenient to install various assemblies and parts on the vehicle, and it is also convenient to change the vehicle type and refit it into other vehicles.

5. The frame has a certain protective effect on the car body.
