Large Vibration Test Facility

The large vibration test facility is used to verify the endurance of a spacecraft stored inside a satellite fairing or onboard equipment against the vibration environments during launch. With vibration load larger than in launch provided by an electrodynamic shaker, the structure of a test item is verified to have no damages caused by vibration environment or no abnormality after the vibration.
The electrodynamic shaker of this facility has a nation’s highest vibration ability with its maximum load mass of 8t, making it suitable for tests on larger test items. It also has many measurement channels , which enable simultaneous measurement on multiple points. Besides this facility, Tsukuba Space Center has a small vibration test facility, which together offer options of facilities to users depending on the size of a test item or intended test purposes.
