摘要/Abstract

摘要： 为研究自行高炮行进间射击时的炮口响应特性，基于多体系统动力学、车辆地面力学、火炮发射动力学建立了自行高炮行进间发射动力学模型，运用谐波叠加法，对典型的自行高炮行驶路面进行重构。通过数值计算获得了不同行驶和射击工况下的炮口响应，分析了行驶速度、路面等级、射击载荷、射角等因素对自行高炮的炮口响应的影响。考虑了自行高炮结构非线性因素，运用有限元方法和接触碰撞理论，将柔性身管模型和滚珠座圈大规模接触碰撞模型应用于模型中。计算结果表明，随着行驶速度和路面等级的提高，炮口动态响应增大，行进间不同射击工况下，炮口响应情况有较大差异。研究结果为掌握自行高炮行进间射击炮口扰动规律提供了参考依据。

Abstract: To study the response characteristics of muzzle for self-propelled antiaircraft gun firing on the move, a dynamic model of self-propelled antiaircraft gun is established based on multi-body system theory, vehicle terrame chanics and gun launch dynamics. The stochastic road irregularities are simulated by means of the sinusoid superposition method. The muzzle responses in the conditions of driving and launch are obtained by numerical calculation. The effects of driving speed, road grade, launching load and firing angle on muzzle response of self-propelled antiaircraft gun are analyzed. The finite element method and the collision theory are used in consideration of the structural nonlinearity factor of antiaircraft gun, and the flexible barrel model and the contact model of ball bearing are applied to the dynamic model. The results indicate that the muzzle dynamic response increases with the increase in travel speed and road grade. The muzzle disturbances may vary greatly under the different conditions of launching. The results provide reference basis for grasping law of muzzle disturbances for self-propelled antiaircraft gun firing on the move.
