The forming of cylindrical parts with the spherical bottom and flat bottom was compared and analyzed. The forming limit height of cylindrical parts with the spherical bottom and flat bottom was studied by using the combination of physical experiment, theoretical calculation, numerical simulation and numerical fitting. On the basis of the calculation method of the forming limit height of the fiat bottom cylinder part, an algorithm for calculating the forming limit height of the spherical bottom cylinder part was put forward, which was expressed by the formula.The correction coefficient of each influencing factor was obtained by means of numerical simulation. The results were verified by an engineering example, and it is proved that the algorithm is reasonable to calculate the forming limit height of the spherical bottom cylinder parts.
