Fuzzy Reliability Design of Robot Parts Based on Weibull and Normal Distribution

With considering lightening and safety of strength, integrations of both distributionpsilas density and functionpsilas density, the normal fuzzy reliability formulas about robot parts that forces are normal distribution, strengths are Weibull distribution and subordinate is gamma function was gotten; first integral change was achieved according to initial data and function imported and extent of integrated, second the 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 robot parts for rising up level of design.
