“…The bending modes are the same in the X and Y directions, which can be explained from simple strength-of-materials beam theory [6] by the fact that, for any cross-section of the mast, the moment of inertia is the same in all directions. The measured structural characteristics of coilable space mast applied on gravity-gradient micro-satellite, in particular the deployment forces and the bottom of the tangential acceleration, should be useful in the design of dynamics and control of spacecraft that employ this type of structure.…”

BUAA Student Micro-satellite (BUAA-SAT) is a gravity-gradient stable satellite depending on a coilable mast. The mast , used as the main deploying and supporting members, plays an important part on the whole satellite structure. What's more, deployment test and modal parameter identification results are two important factors of the deployable space mast. This paper describes deployment test and analysis of the mast, gains modal parameter results through the software Patran and Nastran. Compared to the test with hammering method, the models correlate with test data for low frequency modes, but fall short for higher modes. Through this new method, we find a solution to test large masts with very low first frequency.

“…It is further assumed that the battens always maintain their post-bulked state and thus exert the constant tension force at the joints. The effects of damping and gravity are neglected [6] . The mass is modeled by concentrated masses located at the joints.…”
