The rear door of the wheeled armored vehicle is a part that provides a passage for the crew to get on and off when it is opened and plays a role in forming watertightness and airtightness when it is closed. A case where the rear door was deformed during the rear door opening/closing operation occurred. The rear door should be improved because when it has been deformed, it is impossible to form watertight and positive pressure so that damage for humans and repair cost may occur. Therefore, in this paper, the causes of deformation were analyzed, and improvement plans were derived in order to prevent the deformation of the rear door of wheeled armored vehicles. In addition, a verification test was conducted to evaluate the appropriateness of the improvement plans.
