摘要:
针对侵彻战斗部由引信控制靶后起爆与控制自适应炸点的问题,提出一种新方法,采用冗余弹簧振子结构的惯性开关提供的闭合信号作为控制器感知信号。基于对弹簧振子系统的数学模型分析,总结了在半正弦脉冲加速度信号下质量块的运动轨迹与加速度脉冲的关系。设计了一种感知侵彻过程中弹体状态的惯性开关,并通过ADAMS进行了运动学仿真分析。对所设计的惯性开关进行了实弹侵彻单层和多层混凝土靶试验。采集到了侵彻过程中的加速度信号及与之对应的惯性开关状态信号。试验数据表明:惯性开关能够可靠感知弹体入靶及出靶信息,可作为引信的冗余炸点控制依据,提高起爆的可靠性。
Abstract:
To solve the problems of controlling the burst behind targets and adaptive burst points by detonating fuzes of penetrating warheads,a new method is proposed.The contact close signals obtained from inertia switches with redundance spring oscillator structure are used as the perception signals of controllers.Based on the mathematical model analysis of spring oscillator systems,the relationship between the movement trajectories of the mass blocks and the acceleration pulse is summarized under the condition of half positive sine pulse acceleration signals.An inertia switch is designed,which can perceive the state of projectile bodies in the processes of penetration,and the kinematic simulation analysis is performed by using ADAMS.Experiments of ammunitions penetrating monolayer and multilayer concrete targets are carried out using the inertia switches designed here.The acceleration signals and corresponding state signals of inertia switches during the process of penetration are collected.Experimental results show that the inertia switch designed here can reliably perceive the information of projectile bodies penetrating into and passing through the targets,which can be the control basis of the redundance burst points of fuzes and improve the burst reliability.
