摘要：
To study the effects of vehicle state and vehicle vibration on the firing dispersion of machine-gun and reduce the adverse effects, the dynamic model of a vehicle large-caliber machine-gun was established based on multi-body dynamics, vehicle-terramechanics and gas dynamics theory. The stability of vehicle and the muzzle vibration while the car is free and braked were analyzed, and the effect of different tire stiffness on the firing dispersion of machine-gun was compared. The analysis shows that braking the tire of the car or improving the stiffness of tires are benefit to improving the firing dispersion of vehicle machine-gun. The study result provides a direction for the use of large-caliber vehicle machine-gun and the optimization of overall design.
