Analysis program as well as the analysis method and the cumulative error analysis device

摘要

PPROBLEM TO BE SOLVED: To analyze a cumulative assembly error caused by deformation by the gravity of members constituting an assembly in a design stage. PSOLUTION: In this cumulative error analysis device, at least one of two members is formed of a member elastically deformable by its own weight, and the cumulative error analysis device analyzes the cumulative error of a specific evaluation portion of the assembled members. Design data of the respective members are input to a data storage part 22 from a data input part 21, a deformed shape when at least the one of the two members is elastically deformed by the own weight is calculated by an elastic deformation arithmetic part 23 based on the design data stored in the data storage part 22. Based on an arithmetic result thereof, the cumulative error including the elastic deformation in the specific evaluation portion of the two members when assembling the members is calculated by a cumulative error arithmetic part 25, and an arithmetic result is output to an output display part 26.
