摘要
为了定量地计算形状复杂的钟形橡胶弹簧的刚度,借助阶跃函数建立了钟形橡胶弹簧的轮廓线方程,并利用变分原理和卡氏定理导出其轴向刚度计算公式,可获得较好精度。
In order to quantitatively calculate the stiffness of the complicated bell shape rubber spring, we set up the outline equation of the spring by means of the step function and derive the axial stiffness calculation formulas with the help of the variation principle and the second Castigliano's Theorem.
