摘　　要：文章围绕大能量武器系统连续发射的热管理需求,开展了轨道内部流道的优化设计研究。以最小化轨道膛内表面温度为优化目标,同时约束轨道在发射力作用下的应力与形变,构建了冷却流道的拓扑优化数学模型。以典型发射结构为研究对象开展流道拓扑优化设计,在优化轨道中冷却流道呈椭圆形截面,并集中分布在轨道膛内表面和底面附近。与具有常规圆柱形流道的基准轨道相比,在保持轨道形变和应力基本一致的情况下,优化轨道的截面最高温度降低13%,截面平均温度降低9%,验证了文中提出的武器系统轨道冷却流道拓扑优化设计方法的正确性和有效性。For the thermal management of sequentially fired large energy weapon systems,this paper studies the topology optimization of internal cooling channels of rails.The minimization of the temperature of the rail surface in bore is taken as the optimization objective function.The rail stress and deformation under the launching force are used as the constraint conditions.The mathematical model for the topology optimization of cooling channels is then built.Case study is performed base on a typical launcher structure and optimized cooling channel design is obtained.In the optimized rail,channels have elliptical cross-sections and are distributed close to the surface in bore and the rail bottom.A rail with cylindrical cooling channels is taken as a benchmark structure.Comparing with the benchmark rail,the cross-sectional maximum temperature of the optimized rail decreases 13%and the cross-sectional average temperature decreases 9%,while the load-bearing performance is kept almost the same.The topology optimization method for the design of weapon system cooling channels developed in this paper is hence validated.
