摘要
针对目前中国纺织机械研发模式单一、自动化水平不高等现状,将先进的数字化设计方法应用于织机设计,介绍了虚拟样机技术和喷气织机系统构成。以主流CAD/CAE软件为平台,采用"自顶向下(TopDown)"模式对喷气织机五大机构进行几何建模与装配设计,成功开发了针对喷气织机整机的虚拟样机研究平台。在此基础上,实现了打纬-开口机构的柔性化建模与动力学仿真,并对机架冲击载荷、筘座角加速度及其3D频谱进行了计算与分析,为织造过程的减振降噪提供了有力依据。
In view of unitary design mode and low automation level of textile machinery in our country,advanced digital design method is applied in loom design,and virtual prototype technology and system constitution of air-jet loom are introduced in this paper.Mainstream CAD/CAE software serves as the platform.Geometry modeling and assembly design of five mechanisms of air-jet loom are achieved through ＂Top-Down＂method.In this way,a research platform of virtual prototype for the whole air-jet loom is developed successfully.On this basis,flexible modeling and dynamic simulation of beating-up and shedding mechanism are achieved,and then impact load on frame,angular acceleration of sley and 3D spectrum are calculated and analyzed.Thus,a reliable basis is provided for vibration and noise reduction in the weaving process.
