Abstract:
One of the key issues in the operations of on orbit servicing to unmanned satellites is to provide a safe and reliable docking process. In this thesis, the dynamic behavior of a flexible probe in the central docking mechanism of unmanned satellites is investigated. For this purpose, first a dynamic analysis software has been applied to build a three dimensional model with the assumption of flexible clamped beam as a shock absorber, finally, the impact phenomone is simulated. therefore, in addition to solving a three-dimensional problem and studying the impact phenomenon between chaser and target satellite, it is possible to consider the parameters such as the type of connection between the beam and the concentrated mass, friction coefficient and flexibility of the satellite body in order to determine the optimum condition to apply the least collision force to the satellites
