基于MSC.Marc分析的模型相似关系研究

The study of model similarity relation based on MSC.Marc

运用大型非线性有限元分析软件MSC.Marc分别对原型和模型建立有限元分析模型,对其进行了地震作用下的动力响应分析。通过从加速度、位移、应变等方面对比原型和模型的动力响应,验证了模型和原型动力相似关系的准确性。

Using large nonlinear finite element analysis software MSC. Marc respectively establishes the finite element analysis models of prototype and model structures, to do dynamical analysis under seis- mic action for prototype and model. By comparing the dynamic response for acceleration, displacement and pile body strain of prototype and model, the accuracy of similitude relationship between model and prototype construction is verified.
