【摘要】 针对特征造型系统中约束求解机制所存在的问题,分析了优化法在几何约束求解中的 优缺点,给出了一种几何约束加权求解优化目标函数,以解决目前优化法在几何约束求解应用中的 不足,并给出应用实例.实例结果表明,该函数确保了优化法得到的结果与给定的初始值相接近,能 较好满足设计者的意图.更多还原

【Abstract】 According to the limitation of the current feature modeling system’s constraint resolution mechanism. The paper analyzes geometric constraints of feature modeling of advantage and disadvantage, puts forward a kind of optimization objective function based on the application of optimization algorithm in the solution of geometric constraint and does a simulated experiment, this result of the experiment show that the result of optimization is close to the initial value and satisfies designers finely.更多还原
