NURBS-ENHANCED FINITE ELEMENT METHOD

, 2006
An improvement of the classical finite element method is proposed. It considers an exact representation of the geometry by means of the usual CAD description of the boundary with Non-Uniform Rational B-Splines (NURBS).

Trajectory Planning of Manipulators Based on Artificial Immune-improved Particle Swarm Optimization Algorithm

Jixie chuandong
The trajectory of the welding robot is complex and the control accuracy is high. A trajectory planning method is proposed to meet the multi-objective constraints. Aiming at the requirement of robot trajectory smoothness, the Cartesian space waypoints are

Fitting Surface of Free Form Objects using Optimized NURBS Patches Network with Evolutionary Strategies (µ + λ) − ES

, 2008
We propose an algorithm to produce a 3-D CAD model from a set of range data, based on non-uniform rational B-splines (NURBS) surface fitting technique. Our goal is to construct continuous geometric models, assuming that the topology of surface is unknown.
