电磁线圈发射器相似模型研究

Research on the Scaling Model of Electromagnetic Coil Launcher

模型实验是研究电磁线圈发射器工作特性的有效方法,将模型实验结果应用于电磁线圈发射器原型的研究,必须要弄清模型与原型各物理参数间的相似关系。以电磁线圈发射器数学模型为基础,根据相似理论推导出电磁线圈发射器模型与原型各物理参数的相似关系,设计一种新型的电磁线圈发射器并对该发射器的相似模型进行仿真研究。研究结果表明:电磁线圈发射器各物理参数的相似系数均可由尺度比例系数表示且与尺度比例系数成函数关系,电磁线圈发射器相似模型是成立的。

Model experiment was an effective method to investigate the working process of electromagnetic coil launcher（EMCL）. Model experiment results were applied to prototype study of EMCL after the scaling factor relations of physical parameters between model and prototype were mastered. Based on mathematical model of EMCL and similarity theory the scaling factor relations of physical parameters between model and prototype in EMCL were deduced. A new type EMCL was designed and its scaling model was researched by simulation. Research results show that the scaling factor relations of physical parameters are expressed as fuctions of the length scale factor. The scaling model is rational.
