An NURBS-based isogeometric analysis model for soft EHL contacts

Friction
This paper presents a non-uniform rational B-splines (NURBS)-based isogeometric analysis (IGA) framework for modeling both hard and soft elastohydrodynamic lubrication (EHL) contacts under the fully flooded condition.

Automatic constraint-based synthesis of non-uniform rational B-spline surfaces

, 2018
In this dissertation a technique for the synthesis of sculptured surface models subject to several constraints based on design and manufacturability requirements is presented. A design environment is specified as a collection of polyhedral models which represent compo­ nents in the vicinity of the surface to be designed, or regions which the surface ...

Research on How the Knot Vector Influences Non-uniform Rational B-spline Curve

Chinese Journal of Mechanical Engineering, 2008
Based on the non-uniform rational B-spline(NURBS)curve theory,the general rule of how the knot vector affects the shape of the NURBS curve is put forward.The local support property on how a knot affects the NURBS curve is demonstrated.The quantitative computation formula on how a knot affects the NURBS curve is obtained.An experiment performed on the ...

Feed Rate-Adaptive Predictive PH Interpolation for Real-Time NURBS Toolpath Execution in High-Speed CNC Machining

Measurement Science Review
This study presents a novel feed rate-adaptive predictive interpolation algorithm that combines Pythagorean-hodograph (PH) curves with non-uniform rational b-splines (NURBS) to improve real-time toolpath generation in high-speed CNC machining.

STRUCTURAL SHAPE OPTIMIZATION BY ISOGEOMETRIC BOUNDARY ELEMENT METHOD

Jixie qiangdu, 2019
In Isogeometric boundary element method（IGA-BEM）, Non-Uniform Rational B-Splines（NURBS） which are used for describing the geometric boundary in a computer-aided geometric design（CAGD） are employed as shape functions of Boundary Element Method.
