卫星结构多种多样,用途也各不相同,但从功能上看大都由以下几部分组成:承力部件、外壳、安装部件、天线、太阳电池阵结构、分离连接装置。为了达到多用途和提高经济效益的目的,后又发展出公用舱结构。承力部件:它与运载火箭相连接,承受发射过程中的推力和变矩,因而需要有很高的强度和刚度。承力部件采用铝合金、钛合金和碳维复合材料等。 The structure of the satellite is varied and the uses vary. However, most of the functions are composed of the following components: load bearing components, housings, mounting components, antennas, solar array structures, and disconnecting devices. In order to achieve the purpose of multipurpose and raise the economic efficiency, then developed the common cabin structure. Bearing components: it is connected with the launch vehicle to withstand the thrust of the launch and torque transformation, which requires high strength and stiffness. Bearing components using aluminum, titanium and carbon-dimensional composite materials.
