Abstract: The numerical simulations of different grade random roads are carried out using autoregressive (AR) model, and the travelling and launching integration models of vehicle-mounted antiaircraft missile based on flexible multi-body dynamics are established. According to the simulation results of vehicle dynamics, the worst missile launching time is established. The launching dynamics simulation is conducted and the missile attitude parameters are obtained based on the analyzed results. The effect of velocity and road condition on launching accuracy is analyzed. The research results show that all the three vehicle speeds on B-grade road can ensure launching safety, but vehicle speed on C-grade road is restricuted to 25 km/h.

Key words: ordnance science and technology, antiaircraft missile, AR model, launching on the move, launching accuracy
