COSMOS helps test diagnostic equipment for space travel

Company Innovision Industry Aerospace/Defense Location Denmark Product Used COSMOSM Type of Analysis Linear Static, Advanced Dynamics More Details

The analysis had to make sure that the equipment's fundamental eigen-frequency exceeded 36 Hz - to protect the equipment from resonance caused by vibration during the space shuttle launch.

The Challenge
The European Space Agency (ESA) commissioned INNOVISION, a leading designer of medical equipment from Odense, Denmark, to develop health monitoring equipment that would allow ESA check the affects of weightlessness on astronauts in the zero gravity conditions of space flight. They needed to make sure the equipment would survive the resonance caused by vibration during space shuttle launch.

The Solution
INNOVISION conducted a series of linear static and dynamic analyses to gain information about affected masses and mass moments of inertia, and then conducted advanced dynamics analysis for modal mass.

The analyses showed that the equipment would be unaffected by launch vibration, and a lab sweep test verified those results.

Summary and Metrics:

• Analyzed a wide variety of models ranging from 7,000 through 20,500 degrees of freedom
• Reduced physical prototypes
• Accurately predicted real world behavior of the part
