Abstract:
Test method and simulation technology of the non-full loading firing dispersion for multiple launch rocket system(MLRS) are studied.A new test method for reducing rocket consumption in dispersion test of MLRS is presented.Launch dynamics and transfer matrix method of multibody system are used to develop a launch dynamics model,equations of vibration characteristics and dynamic response.The firing dispersion test method of a non-full loading fire rocket based on the idea of equal initial disturbance is presented.The firing dispersion and the precision of a MLRS are simulated.The simulation results are validated by test results.The initial disturbance of full loading and non-full loading firing scheme is simulated.The simulation results show that the equal initial disturbance is the precondition for the equal firing dispersion.The number of rocket consumption in firing dispersion experiment of a MLRS can be decreased by 75% using the non-full loading test scheme.
