| Abstract: | Modern industrialized large-scale machinery and equipment are mainly crane machinery,and the truss structure is the main component of the crane.The truss structure designed by the traditional design method has a large accuracy error,and the optimal structure cannot be obtained,which will shorten the service life of the crane.This paper uses an improved genetic algorithm to optimize the main beam of the crane.The results show that the improved genetic algorithm shortens the convergence time,the total mass of the crane main beam is reduced by 12.34%after optimization,and the maximum displacement of the crane main beam after optimization is within the allowable range of the design. |
