步兵战车炮塔振动仿真

针对某型履带式步兵战车火炮射击精度受炮塔振动影响大的问题,在ADAMS/ATV和SolidWorks环境下建立了简化后的战车-路面系统虚拟样机;建立了基于谐波叠加法的随机等级路面模型;分析了虚拟样机中主要的力学模型;引入了驾驶员模型控制器,对步兵战车2～5档在B～E级路面上行驶过程中炮塔的振动进行仿真。仿真结果表明,采用虚拟样机对炮塔振动分析的方法是有效的,为炮塔乘员的舒适性研究及瞄准线稳定分析提供参考依据。

Vibration Simulation of Infantry Combat Vehicle Turret

Focused on the problem that gun firing accuracy was influenced largely by turret vibration of a certain typetracked infantry combat vehicle, a simplified virtual prototype of infantry combat vehicle-road system was establishedunder the ADAMS/ATV and SolidWorks environment. The random grade road model was created based on the harmonicsuperposition method is established. Main mechanical models of virtual prototype were analyzed. Driver model controllerwas introduced, turret vibration of infantry combat vehicle when running on B to E grade road with 2 to 5 gear speed wassimulated. The result indicates that it is effective to analyze turret vibration by using virtual prototype and can provide areference for the research of turret crew comfort and the analysis of the stability of the line of sight.
