PROBLEM TO BE SOLVED: To provide a method and a program for rim roll forming analysis simulation capable of performing the analysis processing of the deformation mode in a short time while maintaining the desired analysis accuracy in a rim roll forming process of forming a wheel rim of a vehicle wheel. SOLUTION: The rim roll forming process is separated and set into a plurality of angular increment steps and movement increment steps, and the angular increment analysis processing for performing the analysis for each angular increment step according to the static implicit method, and the movement increment analysis processing for performing the analysis for each movement increment step according to the static implicit method are successively repeated. Thus, the computation processing of the rim roll forming analysis can be reduced, the accuracy and the consistency of the analysis processing are improved, and the processing time is shortened.
