A Double-barreled Self-propelled Artillery Dynamics Simulation And Stability Analysis

This thesis mainly deals with the dynamic simulation of some large calibre double-barreled self-propelled mortar and the analysis of its firing stability. It will use 3-D modeling software and dynamic analysis software to establish the mortar's 3-D entitative model and multi-bodied dynamic model and run such models in order to obtain the dynamic response in the mortar's firing process.The main part in this thesis can be summarized as following:1. Dynamic analysis of the double-barreled joint recoil system, including the caculation of interior ballistic trajectory, the analysis and the design of the structure of recoil mechanism, the establishment of kinetic differential calculus equation for the joint recoil system and the simulating model by use of the Matlab/simulink software, and the dynamic simulation of this system.2. Reseach on the double-barreled self-propelled mortar's virtual prototype.The 3-D model of the mortar is built by means of the Solidedge software,then switched to ADAMS software, and predigested to define each part's topological characteristic and to add restriction and force to the model. In this way, the self-propelled mortar's simulating model is established.3. Research on the joint simulation of the self-propelled mortar's firing dynamics.The dynamic model can creat ADAMS_Sub module from ADAMS software,put the module into the double- barreled joint recoil system's simulative model, simulate the mortar's firing process and analyze the mortar's dynamic response.4. Analysis of some double-barreled self-propelled mortar's firing stability and muzzle's disturbance.Analyze the simulation data, observe the mortar's movement rules and muzzle's disturbance curve, analyse the mortar's firing stability and muzzle's disturbance, and then evaluate the model's feasibility.
