Assembly tolerance analysis apparatus, assembly tolerance analysis method and storage medium

摘要

First, the assembly population of the probability distribution of the mounting state of each part (within the initial setting range of assembly tolerance) is generated using the Monte-Carlo method. Then, an individual group that meets the design specification designated by a user is detected and the initial setting of the assembly tolerance is modified using the individual group. In this case, sensitivity indicating the modification of the assembly tolerance of which part is the most efficient can also be calculated/presented. Furthermore, how much the modification amount should be can also be calculated/presented.
