摘要：The reliability of crane is an important factor to guarantee the mechanical engineering process normally. This paper used Taguchi method analyzed the reliability of the metal structure weld of the bridge crane whose limit state function is mathematical expression. Then we obtained the minimum reliable welding feet height values of the welds between cover plate and web plate on end beam support surface as well as the weld between main beam and end beam joint under different coefficients of variation. This paper provides a new idea and reference for the growth of the inherent reliability of bridge cranes.
