The gamma fuzzy reliability design of vehicle parts

Abstract

With considering lightening and safety of strength, integrations of both distribution's density and function's density, the normal fussy reliability formulas about vehicle parts that forces, strengths are gamma distribution and subordinate is parabola of exponential k was gotten; First integral change was achieved according to initial data and function imported and extent of integrated, second this number result with VB program in the computer was achieved by using middle-points integral calculus and romberg integration. This program can be used in design of vehicle parts for rising up level of design.
