Abstract：To meet the demands of today's market fast fine design and to solve the bulk material conveying machinery's problem of long cycle of product design and slow process of optimization， we developed a platform of rapid design system for bulk material conveying machinery. Taking the bucket and wheel body of a company's bucket wheel mechanism as an examples， we firstly built parametric dimension driven design models， and then used the finite element analysis software to establish multi-objective optimization models based on the principle of parametric， realized the quick optimization of product design， and improved the design efficiency and the accuracy of the complex steel structure. Finally， the parametric design and parametric analysis of the optimization module were highly integrated and the rapid design system platform was completed. Users can use the interactive interface of the rapid design system platform input parameters to get the product they need. The example has indicated that the rapid design system has good application prospects in the serialization development of bulk material conveying machinery.

散料输送机械在港口、矿山等领域的应用得到了越来越广泛地重视，国内外学者对散料输送机械进行了CAD/CAE方面的研究[1-2].最常见的是以实现轻量化为目的，运用有限元分析[3]，疲劳强度分析[4]，动力学仿真等相关知识对产品进行结构优化设计[5].然而由于散料输送机械的组成零件繁多，零部件之间关联紧密，对产品结构的分析修改以及尺寸参数调整的工作量较大，尤其涉及到产品的优化时，往往会因为研发周期过长，而延误生产及产品交付周期.
