三维CAD/CAE技术在内燃机设计中的应用

3D CAD/CAE technology and its application in internal combustion engine design

机械设计手段从20世纪70年代的手工绘图转向计算机绘图,大大提高了绘图效率和绘图质量。二维CADCAE技术的普及结束了手工绘图的历史,对减轻人工劳动强度,提高经济效益起到了很明显的作用。随着技术的发展,CAD/CAE技术正从二维CAD/CAE向三维CAD/CAE过渡。为此介绍并讨论了三维CAD/CAE技术及其在内燃机设计中的应用。

As the engineer language , the blueprint has brought great convenience to the project design technicians. However, with the development of science and technology, especially the extensive application of computer technology, manual drawings can not meet the requirements of mechanical design. Now, computer drawings have replaced manual drawings from the 1970s and it has improved the efficiency and quality of the drawings greatly. CAD/CAE 2D drawings finished the history of manual drawings, reduced labor intensity and played a very significant role in improving economic efficiency. Along with the development of technology, CAD/CAE technology is transiting from 2D CAD to 3D CAD. This paper aims to introduce 3D CAD/CAE technology and its application in a design of internal combustion engine.
