某车载速射迫击炮自动机动力学建模仿真
|
摘要
为了对车载速射迫击炮进行故障预测和结构优化,针对新型车载速射迫击炮的特点,对其自动机动力学特性进行仿真研究。依据多刚体动力学理论,利用SolidWorks和ADAMS软件建立自动机虚拟样机模型,通过对标准装药条件下的4连发射击动作仿真,获得连发射击条件下的仿真结果,并与试验结果进行比较,同时结合火炮构件的动作顺序,分析了后坐部分和输弹板的动力学特性。仿真结果证明了所建虚拟样机的可信性,可为后续故障预测和进一步结构优化提供参考。
In order to predict the faults and optimize the structure of the vehicle-borne rapid-fire mortars, carry out its automat dynamic characters according to the characteristics of the new vehicle-borne rapid-fire mortars. According to the theory of multi-body dynamics, using SolidWorks and ADAMS software to establish a virtual prototype model of the automata, through the simulation of 4 consecutive shooting operations under standard charge conditions, the simulation results under continuous shooting conditions were obtained, and compared with the test results. At the same time, combined with the sequence of the artillery components, the dynamic characteristics of the recoil section and the shell were analyzed.The simulation results prove the credibility of the virtual prototype, which can provide reference for subsequent fault prediction and further structural optimization.
