摘　　要：由于工况恶劣、受力情况复杂,按传统方法对挡板槽帮进行优化,效果并不理想。把基于有限元分析技术的拓扑优化方法引入到挡板槽帮的设计中,阐述并分析了运用有限元分析方法进行挡板槽帮拓扑优化设计的数学模型和关键步骤。对某型号的挡板槽帮优化结果表明,应用有限元法进行拓扑优化设计是一种有效的优化方法,它可以为挡板槽帮的设计提供重要参考。The baffle as the important part of middle pan exists execrable and complicated going,so it is not better using traditional experience formula method to optimize middle pan.Firstly applies topology technology to the design of baffle by FEA and elucidates the rationale,then brings forward process of the optimization design in the area of middle pan using topology optimization.The results of optimization for some middle pan show that FEA are an available method.It can supply important reference for the design of middle pan.
