摘要
在介绍传统螺杆型线设计方法的基础上,提出了基于测量数据的螺杆型线逆向设计方法。通过三维激光扫描仪测得压缩机螺杆的点云数据,对螺杆扫描数据进行处理,针对螺杆截面数据采用NURBS曲线拟合螺杆型线。最后实现了一种精确反求螺杆型线的方法。
Based on the introduction of conventional design of screw rotor profile, a reverse design method using the measuring data of existing screw rotor profile was proposed. The 3D laser scanner was used to obtain the point cloud data of the screw rotor, the unnecessary data like noise and outliers were removed, the feature points of screw rotor were extrancted and the screw rotor profile was fitted with the screw rotor section data by using NURBS curve, which realize the precisely reverse design for the screw rotor profile.
