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。 In this paper, a continuous model is used to calculate the dynamic parameters of the discrete shear structure. In determining the quality of the continuous model, the principle of kinetic energy equivalency was adopted. When determining the stiffness of the continuous model, the principle of equivalent strain of the shear strain energy was used, making the continuous model of this paper able to be calculated simply and accurately. Shear type structure mass and stiffness distributions are uniform or non-uniform overall frequencies. Two convenient methods for calculating mode shapes are also given in the article.
