【摘要】 现代战争要求武器杀伤效力和打击精确性的统一,本文所研究的某小口径单兵武器采用空炸榴弹取代传统动能杀伤弹,提高武器的杀伤力和命中概率;采用精确的目标测距和引信感应装定技术提高打击精确性。本文以某小口径单兵武器采用的空炸榴弹引信的设计为平台,研究金属管武器中引信感应装定系统的非接触能量和信息传输通道。对其进行理论分析与实验测量,研究其实现设计方法。设计的非接触能量和信息传输通道实现引信能量和装定信息的传输对提高该武器的打击精确性具有极为重要意义;研究成果将丰富非接触能量和信息传输技术的内容,拓展其应用范围。首先本文建立了金属结构体对非接触能量传输影响的等效电路模型,将金属结构体对能量传输的影响等效成映射等效电阻和映射等效电感,分析了映射等效参量的物理意义。然后对所研究的小口径金属管武器的引信感应装定系统的初级线圈和次级线圈的阻抗、初次级引信间互感进行测量,根据实验数据计算金属结构体影响在初级线圈和次级线圈的映射等效参数、耦合系数、初级线圈和次级线圈导线损耗、涡流损耗、传输效率。并结合模型对金属结构体的影响进行了分析,所得结论将为金属管武器引信感应装定系统中分离式变压器的设计提供参考。在对所研究引信感应装定系统分离式变压器理论和实验分析的基础上,实践了以分离式变压器为中心的感应装定系统传输通道的设计方法,设计了可用于某小口径金属管武器的引信感应装定系统传输通道的E类放大器,并对该电路的效率进行计算。对以该电路驱动的分离式变压器的能量传输效率、涡流损耗进行了计算,计算结果显示,以该电路驱动时,分离式变压器的能量传输效率只有0.903%,涡流损耗消耗掉初级线圈输入功率中85.13%,所以在金属结构体存在时,引信感应装定系统的分离式变压器是一种能量传输效率很低的结构。本文研究表明,所提出的采用映射等效参量的方法能够有效的分析金属管武器引信感应系统中金属结构体对非接触能量和信息传输通道的影响。该方法进行实验测量和定量计算相对简单,适于在工程设计中采用。本文提出的等效电路模型完全可以推广应用到类似的非接触能量和信息传输通道分析当中。更多还原

【Abstract】 In modern battlefield, the integration of lethality and the hit precision in one weapon is needed. As the small caliber individual combat weapons studied in this dissertation, instead of the kinetic energy ammunition, fire the high explosive air bursting (HEAB) rounds to achieve high lethality and hit probability; adopt precise target acquisition and fuze inductive setting technology to improve the hit precision.In this dissertation, based on some small caliber individual combat weapons design, studies are made on the Contactless Power and Information Transmission (CPIT) channel of the inductive setting system in weapons with metal muzzles. Analyze it theoretically and experimentally, the design method is studied too. The transmission of information and power of fuze by the designed CPIT channel has significant importance to improve the weapon hit precision. The study will enrich the content of the CPIT technology, and will expand its application field.Firstly, the equivalent electrical circuit model of the influence to the contactless power transmission by the metal components is set up. The influences are mapped to equivalent resistance and equivalent inductance. The signification of mapped equivalent parameters is illuminated. Then, the impedances of the primary coils and secondary coils, and the mutual inductance between the primary coils and secondary coils are measured. Based on the experiment data, mapped equivalent resistances, mapped equivalent inductances, coupling coefficient, conductor losses of primary coils and secondary coils, eddy current loss, transmission efficiency are computed. Analyzing the influence of metal components is made base on the equivalent electrical circuit, some conclusions are listed, they will guided the fuze inductive setting system design in weapons with metal muzzle.Based on the theoretical and experimental analysis, practice a design method which focus on the contactless transformer parameters, a class E amplifier is designed consequently, which could be applied in the fuze setter in some small caliber weapon. The efficiency of the circuit also is computed. The transmission efficient, eddy electrical loss of the contactless transformer drove by the designed amplifier, are computed. The computed result is that the transmission efficient is just 0.903%, the eddy current loss take 85.13% power of the primary coil input power away, so, when metal components exist, the contactless transformer in fuze inductive setting system is a extraordinary component.The research in this dissertation indicate that the equivalent electrical circuit model is a effective approach to analyze the influence of the metal components to the CPIT channel in the inductive setting system, that mounted in the weapons with metal muzzle. This method can procure the theoretical and experimental analysis results conveniently, applicable to utilize in the engineering design. The equivalent electrical circuit model could be adopted in the CPIT channel analyzing.更多还原
