摘　　要：传统方法建立的空气悬架数学模型具有普遍适用性,然而对于具体的悬架匹配性则不理想,所建立的悬架动态系统仿真误差大。运用逆向工程技术对某电控空气悬架实体进行三维模型重构,后期可根据三维模型对数学模型修正以提高仿真的精度。以空气弹簧为例详细介绍建模过程:包括点云数据的获取、处理,特征点的提取及曲线拟合、曲面重构。通过试验验证逆向工程建立的悬架三维模型精度高,符合预期要求,基于UG软件的模型测量数据可作为悬架集成设计和实验研究的基础。The mathematical model of air suspension built with traditional methods has the general applicability, however, it can not match well with the specific suspension and the simulation accuracy of suspension dynamic system built according to the general mathematical model is low. This paper proposes that rebuilding a 3D model for mature electronically controlled air suspension with the reverse engineering and modifying the mathematical model by the 3D model can improve the simulation accuracy. The process of air spring modeling includes that obtaining and managing the point cloud data, extracting the feature point, fitting the curve and reconstructing the surface. This 3D model is so accurate that its measured data based on the UG software can be used as the basis of the suspension integrated design and experiment study.
