Web30. dec 2024 · Spacecraft ground testing is sensitive to the smallest vibrations, can be caused by a multitude of factors. Every structure is transmitting vibrations from internal and external sources. Within the building itself, the heating and ventilation system, fans, pumps and elevators are just some of the mechanical devices that create vibration. In-house vibration test equipment and processes, even for small spacecraft, are expensive and time consuming to set up and maintain. However, due to the general-purpose nature of these facilities, they are quite common within large engineering organizations and universities and are rarely booked-up.
