The Optimum Structure of a Supporting Frame in Used in Mast-Climbing Work Platform

based on the structural characteristics of the truss structure, the mathematical model design model for a truss structure used in Mast-climbing Work Platform is built with Ansys design language, in which the maximum stress is the optimization objective and the bar orientation is the design variable, showing the constraints and loading condition in mathematical matrix expression, on this premise of the stiffness condition meets the requirement, the bar orientation brings about great influence on the truss structure optimizing, the triangular framework optimized to be quadrangle framework, the maximum stress has been decreased by 74.37%.
