摘要
小口径火炮在防空反导近程防御中得到了广泛的应用,要求其在很短的反应时间内,必须实时地通过火控系统及弹药引信的快速信息交联技术实现引信的快速自动感应装定。炮口感应装定和弹链感应装定是目前国内外常用的方式,其中后者更适用于转管火炮,由于装定磁场不规则,理论研究非常重要。初级线圈缠绕在弹链发送器上,次级线圈在引信中,构成电磁耦合回路;采用电磁感应方式将火控信息及时地传递给引信;引信电路经过解码分析得到装定信息,从而实现对弹丸的精确控制。利用ANSYS建立弹链电磁感应装定分析模型,讨论架体材料和输入频率对耦合回路输出的影响,完成了准动态感应装定过程分析,对工程化设计具有指导意义。
Small caliber artillery is widely used in the air defense and short-range anti-missile defense, which requires a very short reaction time. The rapidly automatic induction setting of fuze must be achieved using a rapid information cross-linking technology for fire control system and ammunition fuze. Muzzle induction setting and link-belt induction setting are the common setting methods, and the latter is more applicable to rotary tubular artillery. Since the setting magnetic field is anomalous, the theoretical research is very important. The primary coil is winded on the arc setter and the secondary coil is in the fuze, which form an electromagnetic coupled loop; and the fire control information is transformed to the fuze through electromagnetic induction method in time; then the fuze circuit obtains a setting information after decoding analysis to achieve the accurate control of the projectile. A linkbelt electromagnetic induction setting analysis model was established by ANSYS, the influence of the body material and the input frequency on coupled loop output was discussed, the quasi-dynamic induction setling process analysis was carried out, which have introductive significance for engineering design.
