Vibration Test for Satellites & Space Shuttle
Before launching the satellite & space shuttle it is the most important test. I am writing the article for the sake of budding youngsters. Without doing the vibration if satellites are launched all the components or parts will break up & comeout of the capsule. The world runs on mechanical vibrations. Even a quartz clock runs on vibrations when an electric current pass through the piezo electric crystal, crystal vibrates. This is the principle of quartz clock. Vibration is strong phenomenon on earth. When PSLV lifts off the spacecraft or satellite carried by PSLV experiences 15g condition (‘g’stands for acceleration due to gravity). The condition of accelertion due to gravity is tested by accelerometer. 120 accelerometer are placed near the instrument of space shuttle & satellite so that each part could be tested. If a part or component gets cracked by the vibration while testing they will replace the part & component.
