Abstract

Considering safety and strength of vehicle parts, using integrations of probability density function and performance density function the equation of lognormal fuzzy reliability about vehicle parts was gotten. The stress and strength has lognormal distribution and the subordinate function is a parabola of exponential k. The integral change was achieved based on initial data and function imported. This number resulting from VB program in the computer was obtained by using middle-points integral calculus and Romberg integration. This program can be used in the design of vehicle engineering for raising the level of design.
