| 摘 要： | 研究碳纤维材料索桁架在主体结构位移激励下的非线性振动问题,是空间索结构抗震防震设计的基础.在考虑温度变化的基础上,建立碳纤维索桁架在主体结构位移激励下的非线性振动方程,采用Galerkin原理及Krylov-Bogo1iulov-Mitropolsky法求得碳纤维材料索桁架非线性振动的近似解.在将碳纤维索网与钢丝索网比较的基础上,讨论分析温度、位移激励、振幅、阻尼等因素对索桁架非线性振动的影响,得到碳纤维索桁架振动特性优于钢丝索桁架振动特性的结论.

| Abstract: | It was studied that the nonlinear vibration of cable truss using carbon fiber cables under main structure displacement excitation,and it is the base of earthquake prevention design of cable net.Meanwhile its nonlinear vibration equation was presented on the basis of considering temperature changing.And the approximate solution of nonlinear vibration of cable truss was given used Galerkin principle and Krylov-Bogoliulov-Mitropolsky method.Then something that affects its nonlinear vibration,such as the amount... |
