摘要：
In view of the requirement of deployable solar array with high stiffness lead by dynamic imaging in agile optical satellites, a deployable solar array based on truss stiffener was established with components in high technology readiness level and product readiness level. The design of the deployable solar array involved the transition from open loop mechanism to close loop mechanism, the transformation of fundamental mode of vibration by changing the deployed structure, and sufficient reinforcement of the panel. Furthermore, the scheme was optimized via mechanism analysis. The results indicate that the deployable solar array allows a 4.5 s stable deployment without any interference, and the deployment and lock-in mechanism is feasible and stable. The fundamental mode of vibration is torsion with 6.1 Hz frequency. This deployable solar array can satisfy the requirement of agile optical satellites. © 2017, Science Press. All right reserved.
