Bellows product is an important part in the area of plant engineering, shipbuilding, and petrochemistry. For safety and durability, it is necessary to consider many factors when designing it. This research developed a U-shaped metal bellows design software based on the EJMA 9th Edition manual. We developed this GUI software using MATLAB software to be able to design four types of bellows: Unreinforced Single Bellows, Unreinforced Double Bellows, Reinforced Single Bellows, and Reinforced Double Bellows. We designed the already proven bellows model to verify this software. We investigated the behavior while changing the thickness of the bellows. As the thickness of the bellows increases, the spring rate, thrust force, and stress increase, and fatigue life decreases. This software will help design engineers save time and effort.
