Abstract

In order to know if specific spacecraft equipment and components will withstand the extremely high accelerations and vibrations due to booster disconnection or stage separation using small explosive charges, small scale pyroshock tests have to be carried out before the actual launching of the spacecraft. With these tests, shock and vibration conditions similar to the conditions encountered during an actual launch are created. In this project pyroshock tests will be simulated in order to compare the simulated accelerations with the experimental ones by means of: 1) Time history signal: The time history is usually described in terms of its absolute peak acceleration and its duration; 2) SRS (Shock response spectrum): The shock spectrum respon...
