为了研究高速强冲击恶劣工况对于滚子链运行特性影响及其动力学机理，建立了滚子链动力学模型，并推导求解其动力学方程。以链式自动炮滚子链为例，根据滚子链动力学方程分析出影响滚子链动力学特性因素，并在多体动力学软件RecurDyn中进行数值模拟，获得了预紧力、链节间隙、抽壳力三因素对滚子链传动过程中主动链轮碰撞力和主链节链速的影响规律。结果表明：在预紧力4k～6kN、链节间隙0.05mm、抽壳力越小时，主动链轮碰撞力和主链节链速波动相对较小。该结果对链式自动炮滚子链传动的优化设计提供理论依据。

Abstract
In order to study the influence of working condition, including high-speed and strong impact force, on operation characteristics of roller chain and its dynamic mechainsm, the dynamic model of roller chain was established and the dynamic equations were derived and solved. Taking the roller chain of chain automatic gun as an example, the factors influencing the dynamic characteristics of roller chain were analyzed according to the dynamic equations or roller chain. The multi-body dynamic simulation of roller chain of ammuition conveying mechanism of the chain automatic gun was estabished by applying boundary constraints and contacts in multi-body dynamics software RecurDyn. And the different influence laws of different factors on roller chain transmission process of ammuition conveying mechanism, including preload, chain link cleanrance and cartridge extraction, were researched in this paper. The results show that when preload is 4k~6kN, chain link clearance is 0.05mm, and cartridge extraction force is smaller, the collision force of driving sprocket and chain velocity of main chain are relatively lower. The results provide a basis for the design and optimization for chain transmission of the chain automatic gun.
