ICF冷冻靶中Si冷却臂结构的初步设计

摘要

根据我国冷冻靶系统对Si冷却臂结构设计的要求，以美国国家点火装置（NIF）的点火靶系统为原型，对Si冷却臂进行了初步设计。利用SolidWorks软件建立了Si冷却臂三维实体模型，分别从力学性能、热响应和装配方面对其进行了数值模拟和分析。获得了Si冷却臂臂长、分叉长度和宽度等参数对其性能的影响规律，可为冷冻靶结构的进一步优化提供理论依据与参考。%According to the requirement of the cryogenic target system to the Si cooling arm structure ,the Si cooling arm was primarily designed based on the USA National Ignition Facility (NIF) target .A new three-dimensional model of Si cooling arm was developed by SolidWorks software ,and the simulation and analysis of Si cooling arm in aspect of mechanical property ,thermal response and assembly were made based on the model .A law about the effect of the arm length of Si cooling arm and the width and the length of bifurcation on Si cooling arm was achieved .The research may provide the the-oretical foundation and reference for the further improvement of cryogenic target .
