The Parametric Optimization Design Of The Reclaimer’s Upper Structure

The bucket wheel stacker and reclaimeris a large and continuous type of efficient bulk material handling equipment that is essential to modern industry. The design situation of upper structure as its key part has a vital effect on the working performance of the machine. Existing design often amplifies structure design margin to avoid the damage of structure and the working failure, which increases the design materials and manufacturing cost and goes against the overall stability of the equipment,at the same time it can not save energy and reduce consumption;In the design field of large non-standard product, the accurate and efficient design calculation program is still in need. Therefore, with the aid of cutting-edge computational method, to improve the design of upper structure even bulk material conveying equipment and optimize the lightweight design of structures is of great significance in practical engineering background.In this paper, the main research contents include:1.Three-dimensional parametricdesign: The three-dimensional parametric design of the upper structureofbucket wheel stacker and reclaimeris accomplished with the top-down parametricdesign method,The framework and three-dimensional parameterization modelare completed,finally to the two-dimensional engineering graphics.Complete dockingand automatic Updates from three-dimensional model to engineering graphics are realized.2.Three-dimensional parametricanalysis:The parameterized finite element analysis of reclaimer’s structure is realized through ANSYS software and secondary development language APDL.For bucket wheel material piling and taking machine structure into 3D parametric statics analysis and modal analysis. And then provide efficient computation scheme for the calculation and analysis of structure.3.The parameter inversion: the Latin Hypercube Sampling technical parameters are collected as sample point, and quadratic polynomial with no cross terms of function approximation model is taken to fit the design variables and objective function, and through the genetic algorithm to solve the approximate model inversion, further perfectingthe existing optimization design scheme.The topic has done parameterized optimization design and analysis onthe upper structure of the reclaimer’s key parts. Research results can be well applied in the field of bulk material conveying machinery design, to ensure the quality of products at the same time realize the lightweight, shorten the development cycle of the designer, improve the efficiency of research and development, promote the product seriation production, saving the manufacturing cost, has profound guiding significance for the development of the reclaimer’s and wide engineering application prospects.
