| Abstract: |
| According to polar working environment,transportation and lifting conditions,the 12 m S/X/Ka antenna structure is designed in a light and modular way.Based on ANSYS analysis,the stress and deformation of antenna structure under multiple working conditions are calculated.The total weight of the antenna structure designed is 2.8×104 kg,and the maximum lifting unit is not more than 4×103 kg,which meets the needs of modularization and lightweight,and satisfies the requirements for precision and strength design under various working conditions.It has been applied in the construction of related projects. |
