摘要
为了研究在不同射角情况下射击时重力的分力对采用浮动技术机枪的浮动性能的影响,以ADAMS软件为平台,建立某大口径机枪的虚拟样机模型,并将仿真结果与试验测试数据进行比较,证明所建立模型的正确性,然后在不同射角下对其进行动力学仿真,得到机枪射击过程中枪机框和枪身速度、位移曲线。通过对结果数据的分析表明:在不同射角情况下,机枪都能实现近似定速定点击发,而且浮动性能变化很小。
To research influence of the component of gravity on floating performance of machine gun adopted floating technique under different fire angle conditions when shooting, taking ADAMS software as platform, the virtual prototype model of certain large-caliber machine gun was built and the simulation results were compared with test data, proved the validity of the established model. Then the model was carried on dynamic simulation to obtain machine frame and machine body velocity and position curve under different fire angle. Research results shows that machine gun can realize constant velocity and fixed point firing approximately, besides its performance changes slightly under different fire angle conditions.
