articleAbstract=针对接触式测量靶网在破片速度-空间分布同步测量和少通道数需求,提出了一种基于串-并联组合式电路结构的电阻网靶破片群多参数少通道数测量方法,通过设计双面X—Y型测试靶结构,采用等比数列方式优化电阻值配置,构建了靶网电压响应与破片群着靶坐标的定量映射模型,实现了破片群不同着靶位置和速度参数的有效提取,并以正反面8×8位置网靶为例,通过电路仿真和弹道枪试验对破片作用位置识别功能和速度测量功能进行验证。结果表明,设计的新型双通道电阻网靶仅需两路通道即可实现单破片、多破片着靶位置的可靠测量,位置区域识别结果与实际基本一致,且破片作用于测试电路总线、多个破片击穿靶网正面或反面同一测试区域等特殊工况也能较好识别; 同时对比基于高速摄影获取的破片速度结果,速度测量偏差小于7.61%。可见提出的破片群多参数少通道数测量方法可实现破片群速度-空间分布的同步测量,为破片飞行参数获取提供新的思路。, authors=null, authorsList=null, authorCompany=null, correspAuthors=null, authorNote=null,

针对接触式测量靶网在破片速度-空间分布同步测量和少通道数需求,提出了一种基于串-并联组合式电路结构的电阻网靶破片群多参数少通道数测量方法,通过设计双面X—Y型测试靶结构,采用等比数列方式优化电阻值配置,构建了靶网电压响应与破片群着靶坐标的定量映射模型,实现了破片群不同着靶位置和速度参数的有效提取,并以正反面8×8位置网靶为例,通过电路仿真和弹道枪试验对破片作用位置识别功能和速度测量功能进行验证。结果表明,设计的新型双通道电阻网靶仅需两路通道即可实现单破片、多破片着靶位置的可靠测量,位置区域识别结果与实际基本一致,且破片作用于测试电路总线、多个破片击穿靶网正面或反面同一测试区域等特殊工况也能较好识别; 同时对比基于高速摄影获取的破片速度结果,速度测量偏差小于7.61%。可见提出的破片群多参数少通道数测量方法可实现破片群速度-空间分布的同步测量,为破片飞行参数获取提供新的思路。
