基于虚拟样机技术的经纱张力仿真与分析

Simulation and analysis of warp tension based on virtual prototyping

为深入分析经纱张力产生的原因,在SolidWorks软件中创建经纱张力虚拟样机仿真模型。以平纹织物为研究对象,在COSMOSMotion模块中分别对经纱的拉伸张力、垂直张力和水平张力进行动态仿真与分析,获得织造过程中经纱张力的变化规律,并提出经纱张力在动态变化过程中的分解方法和计算方法。探讨了经纱张力的最大值,通过统计分析得出经纱张力最大值的分布特点和变化规律。另将仿真结果与实测结果做了比较与分析,可为梭口形状的设计提供参考。

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.
