[NorahDella]

Solutions for abnormal noises when opening and closing car doors: 1. Check for aging: Inspect whether the door seals are aged, and it is recommended to replace the seals; 2. Check for foreign objects: Examine the door gaps for any foreign objects, which need to be cleaned out; 3. Poorly fixed components: Abnormal noises caused by poorly fixed components between the door parts can be resolved by tightening the screws; 4. Insufficient body stiffness: Friction between steel plates due to insufficient body stiffness or welding detachment, and it is recommended to have it repaired at a maintenance shop. Design requirements for car doors: 1. Ensure convenience for passengers getting on and off, with the opening angle controlled at around 65 to 70 degrees; 2. No positional interference with other parts during the opening process; 3. Reliable locking when the door is closed, preventing it from opening on its own while driving; 4. Good sealing performance; 5. Large light-transmitting area to meet lateral visibility requirements; 6. Sufficient strength and stiffness to ensure reliable door operation, reduce door vibrations, enhance vehicle lateral collision safety, and prevent door sagging.
