多因素分离过程蒙特卡罗仿真平台设计

火箭和导弹等运载工具在飞行过程中涉及多种分离,分离过程出现问题会导致整个任务的失败。分离过程中分离体受到多种干扰因素和误差的影响,而靶场试验次数有限,无法得到多因素对分离过程的综合影响。设计了通用型的分离模型,建立包含多种力和干扰的分离载荷库,基于蒙特卡罗随机打靶技术,能够对多种分离过程进行打靶分析,得到多因素干扰的影响情况。对某导弹头罩分离过程进行了蒙特卡罗打靶仿真,得到了在多种偏差因素下分离体的运动范围。

Design of separation process Monte Carlo simulation platform considering multiple factors

Launch vehicles such as rocket and missile always experience a variety of separations in flights, and any problem in the process of separations may result in failure of the whole task. The separation process of detached body is influenced by many kinds of interferences and errors, and the trial number of target range is generally limited, thus it is difficult to precisely determine the influence of multiple factors in the separation process. A general separation model is designed, and a separation load library containing many forces and interferences is established. The simulation platform is on the base of Monte-Carlo method which can be used into simulation analysis for many different kinds of separation process, and then obtain the outcome considering the influence of multiple factors. The Monte Carlo trajectory simulation for separation process of some missile hood is carried out and the detached body movement range is acquired.
