摘　　要：本文应用能量原理和座标变换方法对花瓣状弹簧的线弹性刚度特性进行了详细的分析，建立了柔度和刚度矩阵表达式以及计算刚度系数的图表。文中所得的结果可应用于基础隔震体系的设计。This paper deduces the basic formula of stiffness coefficient for linear-elastic petloid spring on the basis of Castigliano theorem and matrix transform method. The expressions of flexibility and stiffness matrix wand diagrams of calculating stiffness coefficients are presented. Such kind of coils are mainly used for building basement as seismic isolation device.
