摘要：为了研究某型车载转管机枪在样机试验中不同行驶工况下连续射击时动力学响应，描述了路面不平度分级表示方法，运用谐波叠加法计算不同等级路面谱并编写随机路面生成程序，生成仿真所需要的路面文件。通过重构三维随机路面模型，选取了B、D、F三级路面对车载转管机枪在不同行驶工况下射击过程进行仿真计算，得出路面和车速对车载转管机枪动力学响应及射击稳定性的影响规律。

Abstract：To study dynamic response of continuous shooting in the prototype experiment under different driving conditions on a certain vehicular Gatling gun, the road roughness classification method was described to calculate different levels of road spectrum and write random generation program by using harmonic superposition method, to generate the pavement documents that the simulation required. Through the reconstruction of the 3D road model, the B, D, F grade roads were selected, a vehicle Gatling gun firing process under different driving conditions were simulated, and the influences of firing stability and dynamic response were obtained on different roads and vehicle speeds.
Key words：vehicular gatling gun；road roughness；driving conditions；launch dynamic
