【摘要】 明确引信保险装置的状态变化规律对空投水雷的设计有着重要的意义,直接关系到水雷的作战效能。要确保空投水雷引信保险装置在入水时可靠动作,就需要明确空投水雷在空中开伞、冲击入水和冲击水底等全弹道冲击过程中所受的冲击过载信号峰值和脉宽。为了获取空投水雷的全弹道冲击过载参数,本文在比较各种测试技术的基础上,提出了基于存储测试理论的放入式的测试技术来获取弹体轴线的冲击过载变化规律和其对引信惯性隔爆装置状态的影响规律,并获得了较为完整的全弹道冲击过载实测数据。本文主要阐述了以下几个方面的问题:首先,深入分析了被测信号的特点和测试要求,探讨了引信存储测试系统的系统设计、采样策略设计、状态设计、电源控制管理等相关理论,提出了冲击过载参数测试系统的总体设计方案,并根据这一方案,我们提出在弹体内放置加速度传感器及存储测试仪、在惯性隔爆装置内放置霍尔传感器,以在同一时刻获取弹体轴线的冲击过载信号和引信解除保险信号。其次,根据总体设计方案,我们详细研究了测试系统的机械装置设计、硬件电路设计及专用软件设计等。其中,为了研究测试装置、引信壳体与弹体装配后在空投过程中的振动对冲击过载信号的影响,我们采用有限元软件ANSYS对测试系统和被测弹体进行了力学模态分析。再次,对整个测试系统的可靠性进行了研究,从关键芯片的抗冲击性特性、电路模块抗高低温冲击特性、整个系统恶劣环境的适应性等三个不同环节进行了试验,验证了整个系统的可靠性。最后,在靶场实弹试验中测得了空投水雷的冲击过载信号和其惯性隔爆装置的解除保险信号,并对测得的冲击过载信号进行了数据处理。更多还原

【Abstract】 Efficacy making clear that the change law of the fuse safety unit state has important significance to theair-drop mine design, which directly affects the battle efficacy of the air-drop mine.In order to ensure thatair-drop mine fuse safety unit can act effectively while air-drop sea mine enters water, we need know theimpingement acceleration signal peak value and pulse width of the air-drop mine in the process of entiretrajectory impingement such as opening an umbrella overhead , impinging entering water and impingingthe water bottom. In order to obtain the bodies axis impingement acceleration change law and the changelaw of the fuse safety unit state affected by the projectile bodies axis impingement acceleration during theair-drop mine entire trajectory impingement, compared with the other various test and measurementtechnology, a new method combined several testing technology was put forward based on the traditionalstored testing technology, and the entire trajectory impingement acceleration testing data was capturedcompletely.The following four aspects of the research were proposed:First, the impingement acceleration characteristic was analyzed under the whole ballistic trajectory,and the requirements under different testing environments were studied. The design theory of sampletactics, states and the power management were probed into and an entire design project on the impingementacceleration measuring system was put forword in this paper. Based on the design project, we putacceleration sensor into the air-drop mine and put hall sensor into the fuse safety unit to obtain the bodyaxis impingement acceleration signal and the fuse safety unit action signal at the same time.Second, based on the entire design project, the machine design, the circuit layout and special usesoftware were studied detailedly in the paper. In order to study the impact of vibration of the measuringsystem, the fuse hall and the mine on the impingement acceleration signal, we adopted finite elementmethod software ANSYS to have carried out modal analysis of Mechanics on the measuring system and theair-drop mine.Third, the reliability of the whole testing system was studied, from the anti-high shock ability of thechips to the high and low temperature impingement characteristic property of the circuit module, and even the adverse circumstances adaptability of the whole system.Finally, the projectile body axis impingement acceleration signal and the fuse safety unit action signalwere got from the test.We have processed the captured impingement acceleration signal data.更多还原
