Analysis of Bearing Capacity of Integral Membrane Radome Supported by Metal Truss

The membrane structure is widely used in radome field because of its light weight, high strength and good wave transmissivity. Among them, the integral membrane radome supported by metal truss is one of the important application directions of membrane structure radome. In this paper a large-scale integral membrane radome which is supported by metal truss and is about to reach its end of life is taken as the research object. Firstly, the method of obtaining important parameters which are used in the bearing capacity analysis and evaluation model is described in detail, such as the overall shape detection of metal skeleton, membrane surface tension measurement and mechanical properties detection of membrane materials. Then, the bearing capacity of membrane structure and steel skeleton of radome is analyzed and evaluated by finite element analysis method. Finally, some reasonable suggestions are proposed for the subsequent use or overhaul of radome based on the analysis and evaluation results.
