摘要
车载炮具备信息化水平较高、战术机动性好、战略机动性优良、综合作战能力强的突出优点。因此发展我国的车载炮总体技术,提升我国车载炮技术的研究水平,将具有非常重要的意义。
本文主要研究车载火箭炮在不同工况下行驶的动态响应,并从车与炮匹配组成的系统角度,研究了行驶的平顺性和通过性。根据多体系统动力学理论,利用RecurDyn软件对车载火箭炮进行了行军时动力学仿真。本文主要包括以下几个方面的工作:①用Solidworks软件建立了包括车体、大梁、驱动桥、铰接件、弹簧钢板、火箭炮底座、回转体、发射箱、定向器、火箭弹等全炮结构的三维模型。②建立车炮系统多刚体动力学模型和将大梁柔性化后形成的刚柔耦合动力学模型两种动力学模型。③运用多刚体模型,针对炮座在越野车平台上的安装位置所引起的动态和静态特性进行了研究。④通过对两种模型计算结果的分析比较,验证车炮行军状态多刚体动力学模型的合理性和刚柔耦合模型相对多刚体模型的完善性。⑤理论分析全炮系统通过各种路况的极限条件,得出不同的5种路面参数,并编出对应的5种路面。对5种路况进行行军分析,获得全炮系统和关键部件的动态响应。
本文所做工作对车载火箭炮行军稳定性和安全性总体方案设计具有很好的参考价值。
Wheeled Artillery has highlight the advantages such as: higher level of information, tactical mobility,and excellent mobility strategy,an integrated combat capability and so on. The development of China's overall Wheeled Artillery technology, in order to enhance China's automotive technology standard gun, will have a very important significance.
This paper mainly discusses about the dynamics response of the wheeled rocket launcher that is caused by the plainness causes under traveling congdition.And according to the system aspect of the matching between the cross-country vehicle and rocket launcher, it also presents the ride performance and passing capability.Based on the Multi-body system dynamics theories, Recurdyn is used to carry on ride dynamics simulation of wheeled rocket launcher.The main contents are as follows:①The three dimension model of the systerm inclding bodywork, beam, drive axle, laminated spring, rocket launcher base, rotating body, the launch box, orientation, rockets.etc has been built in the environment of Solidworks ,which provides the necessary conditions for the building of dynmacis equivalent model.②in order to illustrate the problem better ,multi-rigid-body systerm model,the systerm coupled with rigid bodies and elastic bodies are built .③The dynamic property and static property caused by the the location where the rochet launcher places on of the vehicle ,is studied by multi-rigid-body model.④Compared to two kinds of model computed result ,the result confirmed the multi-rigid body model rationality.⑤Calculate the boundary condition of the five state of roads which the rochetlauncher can pass, and obtain the road spectrum corresponding parameter. Carry on the ride analysis in view of five state of roads to obtain the system and key component's dynamic response.
The main works in this thesis lay solid foundation for the overall program design of the stability and safety of wheeled rocket launcher.
