摘 要中国是一个玩具制造的大国，产量位于世界前列。但不是一个玩具强国，玩具品质不高。玩具设计缺乏创新，质量标准不高，生产未严格按工艺流程，生产中应用现代先进技术不充分，这些因素制约着中国玩具业的整体进展。逆向工程作为一种高效的产品设计方法，可以显著缩短产品开发周期，改进产品质量，在国外已广泛应用工程设计领域，国内在汽车等行业有较普遍应用，在玩具行业应用不甚普遍。将逆向工程应用于玩具开发设计，可以提升玩具品质，缩短研发周期。本文，应用逆向工程对一款电动玩具飞机进行了再设计，通过逆向,玩具飞机外形的云点，对塑料件外形、内部结构进行 CATIA 数模重建，局部优化改设计。玩具飞机在外形上更美观，工艺更合理，并对机械传动部分进行设计。关键词：逆向工程 电动玩具 CATIAAbstractToy industry of China is one of the nations of the largest products of toy. The industry is not the first-rate in the world. The development of toy industry of China is limited by many factors, such as design without innovation, lower quality standard, manufacturing no strict technology and with primitive methods.The reverse engineering (RE) is one of the most effective design methods, which has shorted the cycle of the product design with promoting the quality of products. The method has widely used many industries on aboard. Sheet metal design of automobile has applied the method in China. But the toy industry of China has hardly used the advanced method. Toy design with RE can cost less time and promote the quality of toys. This paper re-designed a toy airplane used a motor with REM under CATIA software, which is one of the most advanced soft of CAD/CAE/CAM. The design has these steps- reversing the model, constructing points cloud, modeling the CAD model, modifying some outer forming and inner construct.The airplane has more beautiful on appearance and more reasonable construct.This paper also designed the mechanical syst...
