Telescopic Boom Structure Optimization Based On Chaotic Particle Swarm Optimization (pso) Algorithm And Finite Element Analysis

As the main working component of telescopic crane, telescopic boom’sperformance and quality, directly affects the stability of the whole machineperformance. Therefore, designing a lightweight, high-performance telescopicboom has become the main path to improve the performance of the crane.Optimal design has been used in the design of the telescopic boom more thantwenty years, but for now just in the rectangular section in the design of boom ismore mature, for other section, is still in the exploration, it is not a complete setof mature boom optimization system, and due to the defects of all aspects of theoptimization algorithm, the optimization effect is not obvious; Theory of finiteelement analysis on the engineering application of mature, but because of thedifferent model simplified and boundary condition treatment, makes thecalculation results deviation is large.In this paper, for the research status, we try to optimize the overall structureof the hexagonal-cross section telescopic boom and the proposed penaltyfunction improved method for processing the constraint functions, chaoticparticle swarm algorithm used in the optimization algorithm proposed in thispaper, the chaos into particle swarm optimization, a new combinationalgorithm——Chaos Particle Swarm Optimization, thereby improving theperformance of the optimization algorithm, and apply it to the metal structureoptimization design of the telescopic boom, the results show that the globalconvergence is better. Using finite element analysis software——ANSYS,eliminating the need for a lot of manpower workload，analysis and optimizationresults for verification comparison.Optimizing design and finite element analysis software developed based onVisual C++6.0. With telescopic boom structure quality as the objectivefunction,to build the mathematical model of the optimization of telescopicboom-section size, using improved chaotic particle swarm optimization(C-PSO)to compile telescopic arm frame optimization design module and dotelescopic boom section size optimization, simultaneously using VC++6.0 calling ANSYS, and the result of optimization is compiled into ANSYScommand stream file and imported into the ANSYS to analyze, constitutes the"finite element Analysis module.The result proves that the optimization result isabout10%lighter than the structure of the original instance, greatly reduce steelusage, and improve design efficiency.
