Abstract
This work presents a study of the effects of modal coupling on the microsatellite UPMSat-2, where some design parameters are modified to achieve different levels of modal coupling. The finite element model (FEM) of the satellite is used to obtain the numerical results such as natural frequencies, interface forces and stresses resulted from the different configurations. The results show an appreciable reduction of the forces and stresses on the main structure when the degree of modal coupling is higher. However, the negative effect is the increase of the stresses on the secondary parts, which can overpass their allowable limits
