At the European Space Agency’s ESTEC Test Center in Noordwijk, the Netherlands, the Hydra shaker table is used for satellite testing. This powerful and precisely controllable shaker table, weighing 18 metric tons, is capable of simulating the vibration forces experienced during a rocket launch. It is used to test items weighing many tons.

The Hydra shaker table is a hydraulically-powered platform made of aluminum that measures 5.5 x 5.5 meters. It is the top surface of the table, and below it is a moveable test table that sits on eight hydraulic actuators, similar to a flight simulator machine. To prevent vibrations from spreading throughout the building, the test table is enclosed within a 1,400 metric ton concrete “seismic foundation” block. This block rests on a set of springs and dampers that isolate it and absorb the vibrations.

By subjecting satellites and other spacecraft components to the simulated vibration forces of a rocket launch, the Hydra shaker table helps ensure that they can withstand the harsh conditions of space. This testing is crucial to guarantee the reliability and durability of the devices. Without the use of such vibration simulators, it would be difficult to accurately assess the performance of these components in real-world launch scenarios.

The European Space Agency continues to use advanced technologies and facilities like the Hydra shaker table to improve the design and performance of satellites and other space-related equipment. These tests help to minimize the risk of failure and maximize the chances of successful space missions. The ESTEC Test Center is an important hub for such testing activities, contributing to Europe’s advancements in space exploration and satellite technology.
