摘要微纳卫星技术凭借其体积小、功率低、成本低等优势在通信、导航、对地观测等领域发挥着重要作用。2012年申请加入欧盟第七框架QB50项目，负责研制了一颗双单元立方星NJUST-1， 2015年9月，NJUST-1同其余49颗立方星由我国长征系列运载火箭发射入轨。42483

随着立方星的任务越来越复杂，一次展开的太阳能电池阵已经难以满足立方星的功率需求。因此，研制大功率的电池展开阵已经成为立方星发展的重点任务。本文针对了立方星尺寸的特点，提出了多次展开太阳能电池阵。在此基础上完成了合页、锁紧释放机构、电池板的详细设计，最终完成了整个方案的设计和solidworks组装。

为了验证方案的正确性和可行性，通过ADAMS软件进行了运动学仿真，仿真过程详细分析了合页展开过程角速度、展开时间、受力等数据。42483

Title    Design and simulation of deployable solar array  on cubesat                                      

Abstract

Micro-nano satellite plays an important role in areas such as communication、 navigation and earth observation with the advantage of small volume、low power consumption and low cost.In 2012, NJUST applied for joining in the EU QB50 project，responsible for a 2U Cubesat named NJUST-1, which was launched by Long March Rocket during September of 2015 together with the other 49 Cubesats. 

With the the task of cubesat becoming more complex, once deployed solar array has been difficult to meet the needs of cubesat. Therefore, the development of high-power batteries to expand the array has become a key task of the development of cubesat. In this paper,we put forward a number of solar arrays unfold.in connection with the size of cubesat. On this basis, I have complete the detailed design of the hinge、the locking and release mechanism and panels, and finally completed the design solidworks assembly program as a whole.

In order to verify the correctness and feasibility of the project,I carried out Kinematics simulation by the ADAMS ,which analyse of the angular velocity 、expansion time、stress and other data of hinge.
