Objective]CE-Bézier surfaces with multiple shape parameters were blended to generate the tractor form surface, so as to solve the problem that complex surfaces could not be described by using one single surface in tractor form design.[Method]A group of CE-Bézier surfaces were constructed and blen-ded. Based on this, different tractor shapes were designed by adjusting the surface boundary positions and the shape parameters.[Result]Multiple design solutions of tractor body shape were obtained quickly.[Conclusion]This method is efficient, convenient, and can be widely used in modern design area.%【目的】用多张含有形状参数的CE-Bézier曲面光滑拼接进行拖拉机造型曲面的表示，解决拖拉机造型设计中复杂曲面无法用单一曲面进行描述的问题。【方法】构建多张CE-Bézier曲面，对这些曲面进行光滑拼接，并在调整各曲面公共边界的位置及其形状参数的情况下，形成不同的拖拉机造型方案。【结果】快速得到多个拖拉机机身造型方案。【结论】该方法高效、易于操作，具有良好的应用前景。
