| Abstract: | According to the dynamic character of isolated structure, a simplified calculation system of spatial lateral-torsional coupling isolated structure is presented in this paper, and dynamic character and dynamic response of the simplified system are studied by using response spectrum method. The simplified model has four-DOF(degree of freedom) ,and its mechanics concept is very specific, which will be more convenient, reliable in qualitative analysis and approximate calculation. At the same time, the influence of parameters on dynamic character and dynamic response is fully analyzed, which lays a foundation for further establishing practical design method. |
