摘要
采用有限元和加载试验技术,考虑天线箱体塔架结构的刚度和稳定性,研究并分析了在外载荷作用下箱体塔架的结构设计问题,并结合试验进行对比,给出箱体塔架结构的最佳设计方案,为现场设计提供依据。
In this paper, the stability and stiffness of antenna frame tower structure is studied, and the problem of structure design of antenna frame tower under loading is als ostudied and analyzed by means of FEM and loading test. Then, comparing the results of simulations and tests, the optimal scheme of frame tower structure is obtained, thus providing a basis for practical design.
