纺材经向运动模态分析

A Warp Sense Motion Model Analysis of Textile Materials

在对纺材试样的粘弹特性测试过程中发现,用集总参数表示的线性力学模型,不能较准确地描述纺材试样的经向运动特性。本文从一维波动方程出发,分析了粘弹特性测试过程中试样的经向运动规律,并提出了纺材粘弹特性测试仪的新设计方案。

Since it is found in the viscoelasticity tests of textile material that the linear mechanical model indicated by lumped parameters does not accurately describe the characteristics of warp sense motion of the tested samples,the characteristics are analyzed here by one-dimension wave equation and a new scheme of the viscoelasticity meter is developed.
