基于Imageware的汽车后大梁反求设计

Reverse design of vehicle back beam based on Imageware

以汽车后大梁为研究对象,介绍了反求设计关键技术以及使用Imageware进行自由曲面反求设计的方法。通过对点云数据的采集、数据预处理、特征线构建以及三维模型重建,介绍了利用Imageware实现汽车后大梁这种复杂曲面的反求设计的整个步骤,还介绍了反求设计的一般设计流程以及在Imageware中进行反求设计的技巧。

By taking a vehicle back beam as a research object, the key technology of reverse design and the method for reverse design of freeform surface based on Imageware were introduced. Through the cloud data collecting, data pre-processing, feature line con- structing and 3D model rebuilding, this paper introduces all the procedures through which the reverse design of complicated surface such as the rear frame of vehicle beam was realized. The general design steps and the reverse design techniques based on Imageware were stated.
