VTF FOR SOLAR ARRAYS
The VTF (Vibration Test Frame) for solar arrays is a mechanical unit used for the assembly, integration and vibration testing of the spacecraft’s solar generators.
The mission's challenge
The combination of several parameters (frequency modes, mass, dimensions) was a significant challenge, which we solved through multiple calculation iterations.
Specificity
The vibration frame also has an integration functionality.Technical characteristics
- Dimensions : 5142 x 2972 x 400 mm
- Mass : 900 kg
- Environment : ISO 8
- Temperature : 22 ± 3°c
Operational characteristics
The VTF for solar arrays is used to integrate solar generators.
It is equipped with wheels and guard rails allowing the displacement and protection of solar arrays in clean room. Handling interfaces are also realized on this device.
The VTF is also used for SC integration and deployment simulation after vibration tests.
Delivery times
The vibration frame was delivered in 10 months, with the following steps:
- Mechanical study and analysis
- Control tool manufacturing
- Manufacturing
- Qualification tests
Certifications
This equipment complies with European Standard 2006/42/EC and is tested at 2 SWL by an accredited body.
