| 摘 要： | 为了更高效地对电磁轨道发射进行大量的实验研究,分析改进了使用中小口径发射器作为研究对象的模型化研究方法。考虑到材料属性等实验条件的可行性,对电磁轨道发射器进行模型化,分析其电磁场、温度场等物理场以及速度、带载能力等性能指标,提出较为可行的模型化研究方案,并利用Ansoft Maxwell等软件对瞬态情况下的发射器三维模型进行仿真验证。理论推导和仿真结果表明:电磁轨道发射器的模型化研究方法有很多种,在大口径原型发射器中采用电导率相对较低的材料,即可实现与现有的、采用电导率较高材料的中小口径发射器的物理场匹配,且保证速度和单位体积带载能力相同。

| Abstract: | In order to conduct experimental study effectively, the scaling method used in a small or medium caliber railgun launcher was analyzed and improved. In consideration of the feasibility of the experimental conditions, studies on the electromagnetic field and loading capacity were conducted under the condition that the material properties were constant. In addition, related simulations were carried out to prove the scaling model. Results indicate that there are various scaling methods. In a large diameter rail launcher with relatively low conductivity, the physical fields can match the model launcher which has higher conductivity. |
