Modeling design of plow surface based on uniform B spline;

According to the plow surface generation principle, the mathematical model of plow surface is established by using the parameters, then by Pro/E software to establish the virtual plow surface model, based on which the dynamic simulation analysis was conducted, and the resistance curve of surface in the process of plow turning was found.

In this paper, It analysizes Basic properties and FEM of the surface on the basic of LEMLON plough body surface, and Finally finds the defects and weak links of design.

In this paper , we introduced a method to design the plough body surface with three-dimensional parametric design.

Firstly,three traditional different types plough were selected,and then the points of these plough surface were scaled with three-dimension coordinate scale instrument.

Through an analysis of the current situation of the design for the plough surface , according to the special working demand for the plough and the trait of modern design method, the paper studied and put forward a method for the design of plough surface, i.

The mathematical model of horizontal straight-line plough surface was established using three-dimensional parametric by analyzing the design method of plough surface.
