摘要 为研究固定舵二维弹道修正弹的修正能力,采用流体力学分析软件Fluent与机械系统动力学自动分析软件Adams联合仿真方法建立了固定舵二维修正弹的动力学仿真模型。基于鸭舵修正原理提出了仿真环境下鸭舵减旋和测姿的模拟方法,在Adams软件环境下通过在舵片模型上建立Marker监测点实现了对鸭舵实时滚转角的直接监测;应用该仿真方法对横风作用力从1 N增大到10 N的情况进行仿真,相比于无风干扰,横偏增加了36.5%到298.0%;分别对10 N横风作用力、0.5°横向跳角和0.5°定起角干扰下的弹道修正进行了仿真。研究结果表明:相对于无修正情况下的横偏,在10 N横风作用力下的修正量能够达到90%,由跳角引起的横向、纵向落点偏差得到显著降低;通过与半实物仿真实验及实弹射击试验的对比,证明该仿真方法具有一定的合理性。 To investigate the correction ability of two-dimensional trajectory correction projectile with fixed canards,a dynamics simulation model of two-dimensional trajectory correction projectile is established by using joint simulation of Fluent and Adams. The simulation methods for despinning and attitude determination of canards in the simulation environment are presented based on the correction principle of canards. In the environment of Adams,the direct monitoring of real-time roll angles of canards is achieved by establishing Marker monitoring points on the canard model. The crosswind forces increasing from 1 N to 10 N are simulated,the horizontal deviation is increased by 36. 5% to 298. 0% relative to no cross wind,and the trajectory correction is simulated under the interference of 10 N crosswind force,0. 5° lateral angle of jump and 0. 5° angle of jump. The results show that the correction of lateral deflection under the condition of 10 N crosswind force is up to 90% relative to the uncorrected lateral deflection,and the impact lateral and longitudinal deviations under the interference of jump angle can be greatly reduced. The comparison of semi-physical simulation experiment and live firing test shows that the simulation methodhas some rationality,and can be used in studying and testing the two-dimensional trajectory correction projectile.
