| As the international situation,and surrounding countries to our country’ssovereignty violations and territorial dispute becoming more and more serious. It isnecessary to promote the development of weapons and equipment. Among secondnuclear attack weapons Submarine-launched missile has a big strategic advantage anddevelopment space. Submarine-launched missile launch condition is relativelycomplicated.It put forward high demands for the structure of submarine-launchedmissile and ballistic design.This paper provides a submarine-launched missile trajectory simulation researchmethod. And have an numerical simulation on Submarine-launched missile launchprogress, including underwater stage and the discharge stage.Analyzed the parametersof missile body and the environment influence on the ballistic parameters, and provide areference for submarine-launched missile design work.This article make the submarine-launched ballistic missile water modeling andsimulation firstly. Introduces the motion parameters and the coordinate system used inmissile dynamics modeling, and then in the underwater trajectory of the missile bodysystem dynamics and kinematics model, used in the model of fluid dynamics andadditional quality carries on the detailed analysis and calculation, set up the water andwater movement equations, with different speed boat, different depth and differentvehicle speed of underwater trajectory simulation.Secondly, the simulation analysis was carried out on the water trajectory. Andresearch different firing conditions on water and water ballistic motion parameters.Again, the numerical integral algorithm and the coefficient of hydrodynamic effects onwater ballistic motion parameters.Finally, Current wave interference missile model is established, and the simulationprogram was written, waves of different level, current velocity and direction of thecurrent water ballistic simulation, analyzing different ballistic motion parameters ofcurrent wave conditions on the water. Respectively, to study the current waves andcavitation flow around disturbance to the water trajectory motion parameters. |
