Elastic Rod Based Carpet Loop Pile Trajectory Simulation

The 3D simulation of tufted carpet pile loops need to calculate the direction loop pile. By simplifying the tufted carpet yarn into elongated elastic rod, without considering the extrusion between loops piles, applying pressure at both ends of loop pile. By analyzing the elastic rod stress deformation and using Matlab simulate to determine the yarn centerline direction with the flexible line. The simulation results show that the obtained yarn centerline path is consistent with the trend of actual loop pile.
