Abstract—As the automobile has become a major form of everyday transportation, more and more passenger vehicles are on the road each year. Drivers are increasingly at risk of being involved in accidents, and their carelessness behind the wheel often leads to accidents. Most accidents are caused by forward, rear, or side collisions. In the case of a forward collision, the passengers can be protected with the help of the vehicle's frame and engine room to some extent. In case of a rollover accident, the overall stiffness of the vehicle's roof, doors, and pillars ensures that the roof can meet the desired strength requirement, as in a side-collision accident. Roof crush tests are performed to determine whether vehicle's safety cage is sufficiently stiff and rigid to maintain a safe space in the passenger seats in case of an accident. In case of a deformed roof, the vehicle is repaired in a repair shop. Welded joints of the roof replace it with a new one, or they may cut out and repair the damaged pillars & weld back to the roof. These operations, however, may damage the major parts of the car, thereby leading to its depreciation or raising concerns about its overall performance and safety. In this regard, in the present study, roof crush tests were simulated in the same conditions as in actual test environments. The damaged parts and their status before and after being repaired were simulated and analyzed using a commercial simulation software package.
