Dynamic Simulation of Trawler Carried Rocket Launcher Launching

Dynamic simulation of launching of rocket launcher carried by trawler was studied. The model of rocket launcher system carried by trawler was simplified and built by virtual prototype technology. The power spectral density of motion of ship was calculated based on ocean wave energy spectrum, and the movement spectrums of random motion of ship were calculated and created. In ADAMS software environment, the dynamic response of rocket launcher was calculated in cases of transverse wave, oblique wave, head-on wave during firing. The calculation results show that the launching of rocket launcher carried by trawler in cases of head-on wave and transverse wave are preferable. The conclusion provides reference for the rocket launcher system carried by trawler. Furthermore, the calculation results can be taken as basis of firing density of rocket launcher carried by trawler.
