摘要
为了给碳纤维索在空间结构的应用提供理论基础,在考虑温度影响的基础上,研究了碳纤维材料矩形双层索网的非线性主共振问题,建立了碳纤维材料矩形双层索网在外激励作用下的振动控制方程.采用Galerkin原理及KBM法求得了碳纤维材料矩形双层索网的非线性主共振近似解及对应的定解,首次得到了碳纤维材料矩形双层索网中心的层间接触力近似解.在把碳纤维矩形双层索网与钢丝矩形双层索网进行比较的基础上,结合算例讨论分析了温度、外激励、谐调参数、外阻尼等因素对矩形双层索网非线性主共振的影响.算例表明,当轴向刚度相同时,碳纤维索网抗振性能优于钢丝索网.
In order to provide the theoretical basis for applying carbon fiber cable in space structure,the nonlinear main resonance characteristic of carbon fiber rectangle two-layer cable net was studied with considering the effect of temperature.The corresponding vibration control equation under external excitation was established.And the approximate solution of nonlinear main resonance and the corresponding qualitative solution for carbon fiber rectangle two-layer cable net were derived with Galerkin principle and...
