| Abstract: | In terms of the load conditions of space HXMT ( hard X-ray modulation telescope ) and its interfaces with the corresponding artificial satellite, the finite element method is applied to the dynamic anaylisis of mechanical structural platform of HXMT by adopting the FEM software ANSYS. The natural frequencies and modes of system are caculated and illustrated in accordance withthe built solid FEM model. Under the overloading situations caused by the launching of satellite, the maximum stress and strain of the structure are computed and analyzed in detail. It is concluded that the structure of HXMT have enough mechanical strength and stiffness to undertake the scientific mission in the space. Some valubale results are proposed to optimize the structural design of HXMT. |
