【摘要】 布局设计是齿轮传动系统设计中重要的核心问题之一，它的关键在于建立一种有效的问题表　达和求解模型。提出使用膨胀布局方法来解决这一问题。膨胀方法是一种通过构造布局物体　的膨胀和排斥而自适应地求解物体布局位置的计算方法，能够表达齿轮传动的多层结构和复　杂啮合约束，是较好的齿轮传动系统布局求解模型。更多还原

【Abstract】 ： Packing design is an important problem in gear transmission system design,the ke y is to build an effcient representation and solvent model.An expansion method i s provided to solve this problem. Expansion method is a kind of algorith m method that finds positions of packing items by putting expansion and repulsio n operations among packing items.This method can represent multi layer structur e of gearbox and gear mashing constraints,and it is a kind of good solvent mode l for gear transmission’s packing problem.更多还原
