摘　　要：纬编双面移圈织物工艺结构复杂多变,现有系统在进行设计开发时难以直观地展示出织物的组织结构特点。为实现纬编双面移圈织物的组织结构模拟,本文提出了一种纬编双面移圈织物多层弹簧-质点结构模型。首先建立了成圈、集圈、移圈线圈几何结构模型,接着分析了纬编双面移圈织物结构特征,并在传统弹簧-质点模型的基础上构建了多层弹簧-质点模型,然后采用牛顿第二定律和Velocity-Verlet数值积分法求解了多层弹簧-质点模型的最终位置,最终提出了一种纬编双面移圈织物结构模拟的算法流程。本文建立的多层弹簧-质点结构模型能够反映纬编双面移圈织物的组织结构,具有较好的结构模拟效果。Objective The technological structure of weft-knitted two-side transfer fabric is complex and changeable,and the existing system is difficult to intuitively display the structural characteristics of the fabric during design and development.A multilayer mass-spring structure model suitable for weft-knitted two-side transfer fabric is proposed to simulate the structure of weft-knitted two-side transfer fabric.Method Firstly,the geometric structure models of looping,tucking and transfering are established,and then the structural characteristics of weft-knitted two-side transfer fabric are analyzed.Based on the conventional mass-spring model,the multilayer mass-spring model is constructed.Then the final position of the multilevel mass-spring model is solved by Newton′s second law and Velocity-Verlet numerical integration method.Finally,an algorithm flow of weft-knitted two-side transfer fabric structure simulation is proposed.Results An ideal loop model is established for the basic unit of weft-knitted two-side transfer fabric,including looping,tucking and transferring.According to the documentsand the actual fabric characteristics,the relevant parameter relationships of the ideal looping model are as follows:w 1=4w 2=1.3w 3=2w 4,h 1=0.4h 2=1.2h 3.According to the different types of loops,the parameter values of each type value point will change.By adjusting the model parameters of the looping,the loop models of the tucking structure and the transferring structure are obtained.Among them,the model parameter T of the transferring coil is the sum of the total width of the loop w1 and the distance between the vertical lines of the positive and negative adjacent loop.The actual shape of the loop in the weft-knitted two-side transfer fabric were designed and woven,the position of the loop in the fabric loop shifting,and the structural features of looping,tucking and transferring in the fabric is analyzed.At the same time,the force of the adjacent loops in the fabric changes,causing the deformation of the surrounding loo
