摘要：

Mouldboard shape identification is needed to compare and analyse the performance of different plough bottoms. This paper presents a method for describing an existing mouldboard mathematically. The technique used is based on a Bezier form of three dimensional parametric cubics, and it focuses on an algorithm to improve the efficiency of approximation of a theoretical surface and the actual one. The method is well suited to describing mouldboard designs.
