Software Design of Missile Storage Test System for Vibration and Shocking Mixing Test

In view of abnormal environment test such as weapons flight vibration test and abnormal dropping shocking test,the overall functional design of a kind of missile storage test system for vibration and shocking mixing test system was introduced.As for its vibration test unit,the sampling frequency is 10kHz,including 16 channels,and for its shocking test unit,the data acquisition frequency is 500kHz,including 32 channels.The test and control commands and test data transmission of this system are based on USB bus.The software and hardware interface technique,the encoding and decoding technique of test data and the analysis and process technique were described in detail.The system has been successfully applied to a rocket flight test and dropping test,and test data was got effectively,providing data reference for structure design of weapons.
