TOLERANCE ANALYSIS COMPUTING SYSTEM, TOLERANCE ANALYSIS METHOD AND PROGRAM

摘要

PPROBLEM TO BE SOLVED: To provide a tolerance analysis computing system, analysis method and program capable of performing a tolerance design in a design department, previous verification of tolerance accumulation and optimal tolerance distribution. PSOLUTION: A dimension condition setting part 22 defines the dimension tolerance of design data and each component. A primary analysis executing part 13 uses the dimension tolerance defined by the dimension tolerance setting part 22 to execute a primary analysis and calculates distribution and deviation. An optimal minimum gap operating part 14 uses the calculated distribution or deviation to inversely calculate a gap value that satisfies requested quality for a design specification value and calculates an optimal minimum gap value being a gap value that is optimal and minimum.
