    In order to ensure the huge energy for normal working of China Space Station and less weight costs in launching, China Space Station adopted the large area flexible solar array (LAFSA) design scheme. The LAFSA has complex structures and extremely low frequency, and bearing loads produced by multiple large maneuver procedure in orbit running, so the strength check and parameter design for each load carrying component become very important segments for the mission's success or failure of China Space Station. This paper established a simplified linear modal for the flexible solar array of China Space Station from the perspective of engineering applications, and computed the loads of every important component of the flexible solar array in on orbit large maneuver procedures, which can be used as the instruction for strength check and lightweight design of the LAFSA.
