摘要: 模型实验是研究电磁线圈发射器(EMCL)工作特性的有效方法,要将模型实验结果应用于EMCL原型的研究,必须弄清模型与原型各物理参数间的相似关系。以EMCL数学模型为基础,根据相似理论推导出EMCL相似模型的模型设计条件;对发射器的相似模型进行仿真分析;进行了单级EMCL相似模型实验研究,实验测得的放电回路电流、电枢速度均满足相似模型的模型设计条件。研究结果表明:EMCL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;只要给定EMCL原型结构参数和尺度比例系数,可以推导结构相同、尺度不同的EMCL缩比模型的工作特性;也可以根据EMCL缩比模型的结构参数和尺度比例系数反推EMCL原型的工作特性,为模型实验设计奠定了理论基础。

Abstract: Model experiment is an effective method to investigate the working process of electromagnetic coil launcher (EMCL). The model experiment results are used for prototype study of EMCL after the scaling factor relations of the physical parameters of model and prototype are mastered. Based on mathematical model of EMCL and similarity theory, the requirements for designing the model of EMCL are derived. The scaling model is researched by simulation. The experiment verification of the single-stage EMCL is conducted. The simulation of EMCL and experimental results show that the scaling factor relations of physical parameters are expressed as functions of the length scale factor. The working characteristics of EMCL sub-scale model can be deduced if the structure parameters of EMCL prototype and the length scale factors are given, and vice versa. The research results lay the theoretic foundation for model experiment.
