Abstract

While deployable antenna works in space, there are little or no gravity effects on antenna's state, and it is no need to analyze antenna's cablenet system with considerations of gravity effects. But before launching, deployable antenna is to be assembled and tested in ground conditions, so in this situation, it is necessary to add gravity effects to antenna's analysis model to make sure the calculations are still accurate. For this sake, the catenary element that can simulate cable problems in conditions with gravity effects was used in this paper to build the cablenet system's finite element method model for deployable antenna. Firstly, formula of catenary element is deduced based on cable's original length. Then by using this type of cable element, the finite element method model of antenna's cablenet system in ground conditions is set up. And at last, this finite element method model is analyzed in an example, and the results show the difference of cablenet system between space conditions and ground conditions.
