Abstract:
Pyroshock Test is one of important environment tests in satellite design process.pyroshock or pyrotechnic shock is one of loads that exerted on spacecraft and it's subsystems during launch process. pyroshock can cause failure in some subsystems like sensitive electronic parts, solar cells and so on. For this reason it's necessary to make sure about strength of component under pyroshock which can be done by pyroshock simulator.The purpose of this research is to design a pyroshock simulator that can simulate a pyroshock with given SRS (Shock Response Spectrum) for satellite components.Requirements and constraints for design have been defined such as test item dimensions,weight range and also specification of simulated pyroshock.Almost any type of shock simulators does not meet all of our requirements and constraints.After reviewing all existed structures, tunable resonant beam in overall was best option to cover design requirements and constraints. For this reason it used as design base. However the limitation of this type of simulators is test item size and weigh, it has been reduced in this new design with some modification
