| 摘 要： | 本文采用了连续化的模型,计算离散化剪切型结构的动力参数。在确定连续化模型的质量时,采用了动能等效的原则,在确定连续化模型刚度时,采用了剪切应变能等效的原则,使得本文的连续化模型能简单、较精确地计算出剪切型结构质量和刚度分布为均匀或非均匀的全部频率。文中还给出了计算振型的两种简便方法。

THE GENERALIZED EQUIVALENT MASS METHOD FOR CALCULATING SHEARING STRUCTURES DYNAMIC PARAMETERS |
| |
| Abstract: | The paper uses the continuum model to calculate the dynamic parameters of shearing structures. The equivalent principle of kinetic energy is used to define the mass of continuum model and that of shear strain to define energy to define the stiffness of continuum model.The proposed model can calculate simply and accurately all frequencies of discrete type structures.Two simple methods for model calculation are also proposed in the paper. |
