履带式自行火炮发射动力学建模仿真研究

摘要

Aiming at the problem of costing much simulation time when researching the firing dynamics of self-propelled gun,the model of self-propelled gun was established in this paper based on multi-body dynamic theory,contact theory and ADAMS software,after researching typically the modeling method of rack system.The simulation tests on hard-road and soft-road conditions were made based on this model.Through hard-road simulation,the parameters of the model could be considered setting properly in this work condition;compared to the model built by commercial software（such as ADAMS Track Vehicle software（ATV））,the CPU time cost by this model is shorter.Throughout soft-road simulation,the rules of force and motion of the model matched the results of theoretical analysis.The model built in this paper could be further used to firing dynamic characters of self-propelled gun.%针对目前履带式自行火炮发射动力学仿真耗费时间长,以ADAMS软件为平台,基于多体动力学和接触理论,重点对履带系统的建模方法进行了研究,并建立了全炮的仿真模型。基于该模型,分别在硬质地面和柔性地面进行了仿真试验,通过硬质地面的仿真,认为所建立模型的参数设置合理;通过柔性地面的仿真,其受力和运动的变化规律符合理论分析结果;与专业软件建立的模型相比（如ADAMS/ATV）,该模型消耗的CPU时间较短。该模型可以进一步用于履带式自行火炮发射动力学特性的研究。
