چکیده
Simulation research on the launch process of a ship-borne multiple launch rocket system is studied in this paper. First, the power spectrum density of the ship’s motion is calculated based on ocean wave energy spectrum, and the movement spectrums of the ship’s random motion are calculated. Then, the model of shipborne rocket launcher system is built by virtual prototype technology. The launch process in transverse wave, oblique wave and head-on wave is simulated. Third, numerical calculation of rocket projectile flying is done by exterior ballistics theory. Finally, fire density of the ship-borne rocket launcher is obtained with MonteCarlo method. The simulation results are validated by experimental data, showing that the simulation models are accurate and credible.
