Reverse Design and Simulation on Construction Machinery Suspension Based on ALIAS

为解决复杂曲面的逆向建模难以用简单特征或特征曲线拟合来实现这一难题,提出一种基于ALIAS的逆向设计流程以及曲面构建技术。将扫描获取的工程机械悬挂件点云数据导入Geomagic Studio进行优化处理,结合ALIAS、UG软件重建其模型;利用Geomagic Studio对三维模型进行拟合精度检测;对模型进行基于ANSYS的有限元分析。结果表明:该技术降低了复杂零件的生产和研发成本,并缩短了其改进及创新周期。

In order to solve the inverse modeling of complex surfaces,this paper proposes the reverse design flow based on ALIAS and surface construction techniques by virtue of simple features or feature curve fitting.This paper makes optimization process by importing the point cloud data of the engineering machinery suspension obtained by scanning into Geomagic Studio,reconstructs the model with ALIAS and UG software,makes fitting accuracy detection on the 3D model by Geomagic Studio,and makes finite element analysis on the model based on ANSYS.The results show that this technology reduces the production and development costs of complex components and shortens the cycle of improvement and innovation.
