Abstract

The need to adapt a stabilized platform for the aerial recognition devices arises from the continuous and inevitable movements caused by the aircraft's vibrations, the turbulence and the wind that causes the camera's visual axis deflection from the Nadir. This Study reflects a dynamic numerical analysis of the platform's base structure in such way that the forces produced by the engines in the aircraft which are transmitted to the structure by the fuselage can be interpreted and a proposal for a device that diminishes the effect of those forces that are transmitted to the platform can be presented. The base structure was designed to hold up the platform; the main issue with this structure is the low level of impact absorption when it is subjected to vibrations, due to this 3 design proposals were formulated; these proposals were analyzed through dynamic simulations using the software MSC ADAMS. Some of the data used on the models that were developed was taken from previous research and another part of the data was obtained by direct measuring; now for the creation of the geometrical model the software Autodesk
Inventor was used and the dynamical analysis showed that only one of the proposals delivered results that could improve the issues presented at the beginning of the investigation. Based on this a structural analysis was developed for the final proposal applying the Finite Element Method using the software ANSYSA Multyphisics.
