摘　　要：为提高自动炮武器系统发射动力学模型精度,基于实弹射击试验建立支持向量机响应面,对仿真模型进行了修正。应用有限元分析方法建立了双炮身管结构和炮塔结构有限元模型,基于武器系统各部件间的约束关系建立了步兵战车刚柔耦合发射动力学模型;基于相同边界条件,选取自动炮连发射击中典型结构的振动特性搭建了测试系统并进行了实弹射击试验;针对仿真数据与试验数据误差,引入支持向量机响应面方法对步兵战车刚柔耦合发射动力学模型进行了修正。修正结果表明,基于支持向量机响应面的模型修正方法大幅提高了自动炮武器系统发射动力学模型的精度,更准确地反映了自动炮射击过程中的机构动态特性。The automatic gun firing dynamics model was built up and the simulation model was updated by use of the support vector machine response surface method based on the actual firing experiment so as to analyze the influence factor of firing precision.The finite element models of the gun barrel structure and turret structure were established by means of finite element analysis method,and the rigid-flexible cou-pled firing dynamics models of the infantry combat vehicle were set up based on the restricted relationship between components and joints of the weapon system.The test system was established and the actual fir-ing experiment was carried out by use of picking up the typical structure vibration characteristics in the burst firing of automatic gun based on the same boundary conditions.Aimed at the errors between the simula-tion data and the test data,the automatic gun firing dynamics model was updated.The updating results showed that the model updating method can increase the precision of firing dynamic model and more accurately reflect the framework dynamic characteristics of infantry combat vehicle automatic gun during the course of firing.
