摘　　要：分析了织物的拉伸、剪切及弯曲等物理特性,根据织物拉伸形变过程中受力与形变程度关系的非线性特征,提出了改进的质点-弹簧织物模型,使弹性系数分段线性化,有效解决了织物仿真中超弹性的问题,提高了织物仿真的真实感.The physical characteristics of stretch ability, shearing and surface roughness of cloth are analyzed. Based on the nonlinear characteristics between stress and deformation in the process of cloth tensile strain, the improved mass-spring cloth model is proposed. By the linearization of the elastic coefficients segmentally, the hyperelastic problem in the simulation of cloth is avoided, and the reality of cloth simulation is improved.
