| Abstract: | This article aims to study how to compute the distance between curved surface and curve in engineering construct.Taking the unknown coordinate in curved surface and curve as design variables,the equation of curved surface as constrained condition,and the distance between unknown coordinate as objective function,optimization is proposed to minimize the distance between curved surface and curve.With the result,simulation examples are analyzed.The article draws the conclusion that this method can be used to solve engineering and theoretical problems. |
