CubeSat Engineering Qualification Model: Shaker and Shock Testing at Fotec
As part of our ongoing CubeSat development, we recently carried out crucial environmental tests on our Engineering Qualification Model (EQM) at Fotec. These tests are a key step in validating our satellite’s design, ensuring it can withstand the harsh conditions it will face during launch and space operations. Fotec provided invaluable technical support throughout the testing process, helping us set up and actually execute both shaker and shock tests.
Shaker Testing: Successful Across All Axes
The first phase of testing involved subjecting our CubeSat to shaker tests. These tests simulate the intense vibrations experienced during launch, with our CubeSat being shaken along all three axes. Following the specific requirements set by our launch provider, we carefully monitored the satellite’s behavior, particularly looking for any critical shifts in its eigenfrequencies.
We’re pleased to report that the CubeSat passed the shaker tests with flying colors. There were no significant changes in its eigenfrequencies, indicating that the structure remained stable and is capable of handling the vibrational forces of launch without compromising its integrity.
Shock Testing: An Area for Further Investigation
Following the shaker tests, we moved on to shock testing. This phase simulates the sudden, high-impact forces that the CubeSat may encounter during events like stage separation or deployment. While the CubeSat performed well overall, we did observe one change during the shock tests that requires further analysis.
Thanks to Fotec’s expertise and technical advice, we are now thoroughly examining the results to determine the cause and impact of this change. Their guidance has been instrumental in helping us interpret the data and chart a path forward.
What’s Next?
We are now focused on a detailed review of the shock test results to ensure that any potential issues are fully understood and addressed before moving forward. With Fotec’s continued support, we are confident in our ability to finalize the CubeSat’s design and ensure its readiness for the challenges of space.
Stay tuned for updates as we continue to analyze the data and prepare for the next phases of our CubeSat mission!
