摘要
针对特征造型系统中采用的约束求解机制所存在的问题,依据自由度分析和遗传算法理论,分析了语义特征造型中的几何约束,提出了简化约束方程组并对非线性方程组进行求解的方法,应用到HUST-CAIDS中,保证了求解结果的正确性和稳定性.
According to the limitation of the current feature modeling system's constraint resolution mechanism, this paper analyzes the geometry constraints of semantic feature modeling based on freedom degree analyze and genetic algorithm theories, presents the methods of simplifying the constraint equation groups at first, then solving non -linear equation group. The study has been applied to the HUST -CAIDS and guaranteed exactness and stability of the results.
