Modeling and 3D simulation of circular section braided fabrics
Based on the analysis of 2D circular and 3D two-step circular braiding process and braiding motion law,the common characteristics of the circular section braiding structures were discussed,and the mathematical models of circular section braiding structures were established to simulate the trajectory and spatial position of the single strand center line in braiding structures.Using WebGL technology and 3D graphics engine library Three.js on Visual Studio 2019 platform,the 3D strand braiding structures were presented quickly and effectively,and the 3D simulation efficiency was greatly improved.The results showed that the 3D simulation of the circular braided structures based on the generalized rose curve mathematical models was feasible and effective,which could better reflect the interweaving law and appearance characteristics of the strands of braided structures.The research can lay a foundation for modeling and structural visualization of the braided rope for industrial use.
