在“数值方法”总的思路指导下 ,结合动力机器基础振动的特点 ,把土与基础视作一弹性共同作用体系 ,利用大型工程分析软件ADINA ,分别对简单地基条件下基础不同振型及复杂地基条件下的耦合振动进行了系统的数值试验 ,并将所得的结果与相应条件下由《规范》方法与Lysmer比拟法计算的结果进行了对比分析 ,验证了数值计算方法对于动力机器基础设计的系统性、可行性与优越性
Under the guidance of the general idea of “numerical method”, combined with the vibration characteristics of the foundation of dynamic machine, the soil and foundation are regarded as a flexible interaction system. Using large-scale engineering analysis software ADINA, The numerical simulation of the coupling vibration under the condition of foundation is carried out systematically and the results obtained are compared with those calculated by the Lysmer comparison method under the corresponding conditions. The numerical calculation method is validated for the basic design of the power machine Systematic, viable and superior
