基于MATLAB和AutoCAD的活塞裙部中凸变型面造型

Curved Surface Modeling of Piston Skirt Based on Matlab and AutoCAD

在MATLAB环境下,利用三次样条插值方法得到了活塞裙部中凸变型线。并依据自由曲面造型理论,给出了活塞裙部型面造型及加工数据文件的生成方法,同时生成了相应活塞裙部型面数据文件。并与AutoCAD软件结合,在AutoCAD环境下实现了活塞裙部型面造型。

The middling-convex curve of piston skirt is obtained with the cubic spline interpolation method using MATLAB. According to theory of curved surface modeling, the curved surface modeling of piston skirt and generating method of its machining data are put forward by the soft of MATLAB. At the same time, the data file of the piston skirt is created. With the data file, the curved surface modeling of piston skirt can be gotten with AutoCAD.
