摘　　要：针对某水下航行器(unmanned undersea vehicle,UUV)工作特性,运用Hertz接触理论,推导出齿轮体积与传动比之间的数学模型,并建立该传动系统的空间布局优化数学模型。采用多目标遗传算法(multi-objective geneticalgorithm,MOGA)完成空间布局方案的优化设计,在满足约束条件下,计算出此系统结构参数和齿轮空间坐标。结果表明比现有圆柱形齿轮箱的圆柱面积减少了10.6%,体积减少了8.4%。表明该方法具有很好的工程应用价值,可作为水下航行器减速器设计优化的新思路。In view of the operation characteristic of a certain type of UUV（unmanned undersea vehicle） turbine engine,deduce the mathematic model of gearbox volume relating to transmission ratio using Hertz contact theory,and establish space layout optimization mathematical model.To meet the restrictive conditions,gear structural parameters and space layout coordinates have been got by MGOA（multi-objective genetic algorithm）.The result is that cylinder area of the gearbox is less 10.6 percent than the existing and the volume is less 8.4 percent.All these show that this method has a very good project value,and it lightens a new idea for UUV deceleration product optimization design.
