All calculations right from number of convolutions, width, fatigue life cycle, stress, weight, movement calculations, tie-rod, sleeve, shroud, end pipe length and vibration calculations are done automatically. After the calculations, SPULLOWS also generates manufacturing drawing in ACAD or any other 2D drafting software of the bellows with assembly and child part drawing along with BOM (Bill of Materials), Standards / Schedules used, a 3D model, and costing sheet.
