Abstract

A finite element model of QTZ5010 tower arm is established by using ANSYS parameter design language (APDL), through static simulation, the stress and strain distribution and its strength and stiffness margin is obtained. With the cross sectional dimensions as the design variables and stress and strain of boom under extreme working conditions as restrain conditions, the mathematical optimization model is established. The fuzzy algorithm and genetic algorithm are used to calculate iteratively for minimal mass. Analysis results show that boom mass reduces by 309kg and realizes its structural light-weighting design. Compares with the original structure, the optimized structure strength no significant drop, still meet the requirements of the specification and design of tower crane.
