借助于Cosserat曲线理论定量研究了法线和副法线螺旋弹簧的劲度系数。计算结果表明,在拉伸螺旋弹簧过程中劲度系数并非始终保持定值。并且副法线螺旋弹簧比法线螺旋弹簧有更好的线性弹性性,所以副法线螺旋弹簧更有利于应用在机械系统。
藉助于Cosserat麯線理論定量研究瞭法線和副法線螺鏇彈簧的勁度繫數。計算結果錶明,在拉伸螺鏇彈簧過程中勁度繫數併非始終保持定值。併且副法線螺鏇彈簧比法線螺鏇彈簧有更好的線性彈性性,所以副法線螺鏇彈簧更有利于應用在機械繫統。

With the aid of Cosserat curve theory ,we investigated the stiffness coefficients of normal and binormal helical springs. The results show that the stiffness coefficients are not immune to the elongation in the entire stretching process. The binormal helical springs are quantitatively confirmed to excel over the normal ones in lin-ear elasticity. Therefore,the binormal helical springs are more beneficial to the applications in engineering.
