Simulation and analysis of warp tension based on virtual prototyping

The reasons that cause warp tension are analyzed.The virtual prototype model for warp tension is set up in SolidWorks software.The plain woven fabric is made as object to study,the dynamic simulation and analysis of the stretch tension,vertical tension and horizontal tension of the warp are carried out in COSMOSMotion.Then the law of the warp tension varies during weaving is acquired,and the methods of decomposition and computation of warp tension in dynamic and changing process are put forward.In order to offer a foundation for shedding design,the maximum of warp tension is studied and its distribution characteristic and changing law are obtained by statistical analysis,then analytical comparison between the simulated results and the values measured is made.
