摘要

A deployable CFRP thin shell reflector is being developed for future earth observation missions. Preliminary design shows that it has a high stiffness/mass ratio when deployed, and has potential for further development in order to meet the requirements of harsh environment during launch and in orbit. Hence the study is focused on the structural dynamic analysis of the reflector in folded configuration. The structural dynamic response of the folded reflector is obtained by a whole host of analyses including folding, natural frequency, quasi-static acceleration, sine vibration and shock analyses considering launch mechanical environment.
