Key technologies of dynamic simulation and design for large caliber truck-mounted artillery

Abstract

Large caliber truck-mounted artillery is a popular weapon developed and equipped in recent years because of its advantages of low cost, high mobility and strong firepower. However, in the firing process of vehicle mounted artillery, it is bound to face the problems which traditional towed artillery or tracked self-propelled artillery does not have. Taking a large caliber truck-mounted artillery as object, a whole artillery dynamics virtual prototype is established and three key technologies of dynamics simulation are studied, which are the influence of turret race waggling on the force of elevating equilibrator and other mechanisms, the top-down optimization design method of the spade, and the influence of tire support on firing stability. The results show that the turret race shaking will directly affect the force magnitude and even direction of the elevating mechanism, and the influence of the angular acceleration of the rotating part given by the turret race shaking needs to be considered; In order to achieve lightweight design, the design parameter of the mechanism such as the spade should be taken as the optimal value in combination with the firing stability of the gun. The traditional truck-mounted artillery usually does not take the driving system as the bearing structure during firing, but it is found that when the wheels land and provide a certain proportion of support force, it is helpful to maintain the vehicle body position. The research can provide reference to the dynamic simulation and design technology of related vehicle weapons.
