摘　　要：针对皮肤形变量测量方法存在的工作量大、操作复杂等普遍问题,通过人体体型与关节部位运动时皮肤形变量的关系,并结合数学原理构建人体主要关节的几何模型,分别得到肩关节、肘关节、髋关节和膝关节皮肤形变量的计算公式,然后与现有的测量方法进行对比实验。研究结果表明:皮肤形变量主要取决于关节的围度、活动角度以及身体质量指数;各个关节皮肤形变量计算结果与实际测量结果的平均误差为0.51 cm,在0.05显著水平上无明显差异,从而说明该方法可以用于皮肤形变量的预测,能够为服装结构设计提供参考。Aiming at the common problems of large workload and complex operation in the measurement method of skin shape variables,the geometric models of main joints of human body are constructed through based on the relationship between human body shape and skin shape variables during joint movement.Mathematical principles were used and calculation equations of skin shape variables of shoulder joint,elbow joint,hip joint and knee joint were established respectively,and they were compared with theresults from using the existing measurement methods.The results show that the skin shape variables mainly depends on the joint circumference,movement angle and body mass index.The average error between the calculated results of skin shape variables of each joint and the actual measurement results is 0.51 cm,and there is no significant difference at the significant level of 0.05,which shows that this method can be used to predict skin shape variables and provide reference for garment structurale design.
