摘　　要：为探究运动状态下服装间隙量的变化情况,提出一种基于有限元软件构建的单层服装间隙量的动态仿真模型,模拟步行时的力学状态与间隙量。首先,基于三维点云数据构建人体与服装的不同组织结构形态的三维模型,利用Instron万能拉伸仪与三维动作捕捉系统获取服装材料参数与人体运动坐标,建立人体单层服装间隙量有限元模型,利用有限元仿真软件进行动态仿真模拟,最后将仿真模拟得到的间隙量与真实运动状态下的间隙量进行对比验证。结果表明:建立的有限元模型可精确描述服装动态间隙量变化,且模拟结果与实验结果的最小平均误差值为0.24 mm,最小相对均方根误差为1.81 mm;对同一运动周期6个时间段下2组数据进行相关性分析,仿真坐标值与真实坐标值在0.01水平(双尾)显著相关,证明了动态有限元仿真的准确性。In order to investigate the dynamic change of ease allowance of clothing during motion,a dynamic simulation model for single layer clothing ease allowance using finite element method was proposed,simulating the mechanical state and clothing ease allowance generation mechanism.Based on the three-dimensional(3-D)point cloud data,3-D sub-models of human body and clothing were constructed.Instron universal extensometer and 3-D motion capture system were used to measure the physical properties of clothing and the coordinates of human trunk during dynamic motion,then a finite element model of a single layer clothing ease allowance was established.The finite element simulation software was used for dynamic simulation,finally,the ease allowance obtained by simulation is compared and verified with the ease allowance in real motion state.The results show that the minimum average difference between the simulation and experiment is 0.24 mm,and the minimum relative mean square error is 1.81 mm.The simulation coordinate value is significantly correlated with that in experiment at the level of 0.01(two tails).It indicated that the simulation results can accurately predict the dynamic garment ease allowance around the chest during motion.
