| Minor caliber anti-riot guns have some inadequacies such as low power and close firing rangewhen conducting an anti-riot task.Especially whenin the face of the mass rioters,the minor caliber anti-riot guns can not fight against rioters effectively,so the large caliber anti-riot launchers are needed.Focused on the problem of backward force in large diameter anti-riot launcher,this paper decided to install the groove type hydraulic buffer and muzzle brake of shock type recoil device in large diameter anti-riot launcherafter comparing the different performance between the buffer and muzzle brake.This scheme is used to realize the purpose of reducing the recoil resistance by adopting the principle of recoil buffer.In the scheme,the structure of the buffer and the muzzle brake were designed according to the pressure and velocity curves obtained through the analysis of high and low pressure interior ballistics.The three-dimensional model was built through UG software and the efficiency of the muzzle brake was calculated.In addition,the optimal design model of structural parameters of single target buffer with multiple design variables and multiple constraints is established by using the principle of optimal design,and a set of optimal buffer structure parameters were gotten by computing the MATLAB software programming.Based on these parameters,dynamic model of the launcher is established through the MATLAB software to analyze the motion process of weapon system in dynamics simulation.In order to verify the suitability of the buffer,the motion process of weapon system proceed the dynamic simulation analysis under the condition of different shooting angle.The simulation results showed that the groove typehydraulic buffer and muzzle brake of shock type recoil device in large caliber anti-riot launcher can reduce the recoil resistance effectively in differentshooting angle conditions to realize shoulder firing.Thus,the feasibility of the overall scheme was verified. |
