摘　　要：为实现用更小的导轨电流弹射大质量抛体,基于四极电磁轨道发射器提出了串联增强型四极电磁轨道发射方案,分别建立了增强型发射器的主、副导轨产生电磁推力的数学模型,对电磁推力的特性分别进行了仿真研究,根据预设电磁推力的大小确定了导轨层数的公式,并对传统型和增强型发射器的弹射过程进行了建模仿真。仿真结果表明:增强型发射器的电磁推力在更低的位置能趋近最大值,当大质量的抛体弹射速度相同时,增强型发射器的导轨电流小于传统型发射器导轨电流的60%。To realize the ejection of heavy projectile with smaller current,a series-connected augmented quadruple electromagnetic rail launcher is proposed based on quadruple rail launcher.The mathematics model of electromagnetic thrust generated by the main rails and auxiliary rails of augmented rail launcher is established respectively and the characteristics of electromagnetic thrust are simulated,and a formula of determining the number of rail plies according to preset thrust is given.The ejection process of traditional and augmented rail launcher was modeled and simulated.The results show that the electromagnetic thrust of augmented launcher approaches the maximum at a lower position and the rail current of augmented rail launcher is less than 60% of the traditional rail launcher when ejecting the projectile to same speed.
