Columbus Design, Analysis and Verification Control Approach versus the Micro-gravity Requirement

摘要

The European project manned module Columbus, as part of the International Space Station, has been conceived to allow scientific experiments on micro-gravity environment. In order to face against this challenging design goal, Alenia Spazio developed a dedicated control approach, based on budget allocation of the mechanical power, covering the Design, the Analysis and the Verification aspects from system level down to the equipment one. This control method covers both the evaluations by analysis and/or by testing of the Columbus Structural and Vibro-Acoustic transmission paths and the characterisation of the disturbers (as Environment Control Life System fans, Thermal Control System pumps and valves, etc.) in terms of force at the equipment interfaces and SPL in the surrounding volume. A dedicated methodology on how to derive the induced disturber's interface forcing functions has been developed in the frame of this project.
