在分析机械产品设计过程特点的基础上 ,介绍了多维工程约束在机械产品设计中的描述方法 ,即主要由约束、约束集和约束层三部分组成。给出了多维工程约束的建立过程及其求解方法等
On the basis of analyzing the characteristics of mechanical product design process, the description method of multi-dimensional engineering constraints in mechanical product design is introduced, which is composed of three parts: constraint, constraint set and constraint layer. The establishment process of multi-dimensional engineering constraints and its solution method are given
