【摘要】 在弹道导弹设计的各个阶段,需要进行不同精度的弹道设计和仿真。同时,不同种类的导弹的仿真模型也相差较大。弹道导弹的弹道设计与仿真是弹道导弹总体设计的重要内容,贯穿于弹道导弹研制的各个阶段。同一导弹选用不同姿态的弹道,会有不同的飞行性能。为正确使用和充分发挥导弹的技术性能,需要对弹道进行认真设计。为了得到准确的仿真结果,设计人员需要针对具体问题使用专门软件。针对这一需要,本文致力于弹道设计、编写弹道仿真软件能实现不同类型的导弹在不同的发射方式下,进行不同自由度的多段弹道全数字仿真。为此,本研究主要集中在以下几个方面:1)在理想状态环境下建立弹道仿真所需的子模块,包括坐标转换模块、地球引力模块、标准大气模块、飞行程序模块、发动机模块等。给出了弹道导弹的主动段运动方程、自由段椭圆运动方程和再入段运动方程。分析了引力和附加惯性力等因素对射程的影响。2)论述了用参数选择法求解弹道仿真问题的方法。弹道导弹的弹道求解就是设计俯仰角程序,文中给出了俯仰角程序设计的工程方法。通过选择俯仰角程序的几个特殊参数,将弹道解算这样的动态问题转化为参数选择问题。针对弹道导弹飞行弹道的目标和多种约束要求,建立了参数数学和仿真模型。3)编写程序,以便从输入文本中搜索提取有用数据,并使程序变得更加有效可靠和友好易懂。这有利于弹道设计和仿真等其他软件调用本软件时修改参数。最后,本文结合具体算例对软件的使用进行了简要地说明介绍,验证了软件的可靠性。更多还原

【Abstract】 In ballistic missile design of each phase, the need for different precision design and simulation of trajectory. At the same time, different kinds of missile simulation model is different. Ballistic missile trajectory design and simulation is a ballistic missile is an important content of the overall design, throughout all phases of ballistic missiles. The same gesture of ballistic missile chooses different, can have different flight performance. For the correct use and fully missile technology, need to carefully designed trajectory. In order to get accurate simulation results, the design for specific issues need to use special software.In this paper, a need to ballistic trajectory simulation software design, write to achieve different types of missile launch in different ways in different degrees, of ef ficient digital simulation. Therefore, this research mainly in the following aspects:1) In the ideal environment for establishment of trajectory simulation modules, including coordinate conversion module, gravity module, standard atmospheric module, flight program modules, engine modules etc. Given a ballistic missile active period of motion equation for freedom, the equation of motion and elliptic equations of motion segment. Analysis of gravity and additional force on the influence factors such as range.2) Discussed with parameter selection method to solve the problem of trajectory simulation method. Solving ballistic missile trajectory design elevation Angle is presented, the procedure of the method of engineering program design elevation Angle. Through the choice of several special pitching Angle program, so the dynamic solution trajectory problem into the parameter selection problem. According to the target of ballistic missile flight trajectory, and many constraints, established mathematical and simulation model.3)Program, to extract from the input text search, and make useful data become more effective and reliable program. Friendly This is helpful for ballistic design and simulation software calls the other software modification parameter.Finally, combined with a concrete example of the use of software are briefly introduced, and verifies the software reliability.更多还原
