Abstract

In this paper, design and simulation of a deployment and release mechanism of a communication satellite antenna are described. Because of the simplicity and reliability of the system, a torsion spring is used to excite the antenna. Dynamic simulation is performed by Adams Software and the appropriate spring and damper are selected for the mechanism. Also, a thermal cutter mechanism is used for the release mechanism of the antenna that shows a good performance in the tests. Also, a finite element analysis is performed to ensure the structural strength of the mechanism by Nastran-Patran Software. According to the results of the tests and simulations performed on the system, one can say that this mechanism is a simple, functional and reliable mechanism and can be done well the assigned duties in accordance with the requirements of the employer and the ECSS standard.
