Reverse Modeling of the Helix Roller in the Omni-Directional Wheel Based on NURBS

摘要：

　　The helix roller of the omni-directional wheel was measured by the three-coordinate measuring machine and then the obtained data was preprocessed.The principle of the least squares approximating NURBS(Non-Uniform Rational B-Spline)curve fitting algorithm was analyzed and with this algorithm the contour line of the roller was reconstructed in MATLAB software,thus the outside silhouette surface was generated on the basis of the fitting curve and finally the three-dimensional solid model of helix roller was built in Pro/Engineer.The results laid a good foundation for further finite-element analysis and manufacturing.
