摘要

真空靶室组件的结构稳定性对惯性约束聚变（ICF）装置的束靶耦合精度有重要影响，本文对真空靶室组件的结构稳定性进行优化设计。首先研究真空靶室组件的动态特性，求解其固有频率和振型；其次，分析支墩不同结构参数对真空靶室组件前三阶固有频率的影响，并由此建立结构参数影响固有频率的数学模型；最后，进行真空靶室组件的结构稳定性设计优化，求解真空靶室组件的最优结构。结果表明，优化后真空靶室组件的一阶固有频率为14.44 Hz，满足ICF装置的设计要求。

Abstract

Structural stability of vacuum chamber assembly significantly affects alignment precision of laser beam and target in Inertial Confinement Fusion(ICF) facility. Structural stability optimization for vacuum chamber assembly is processed in this paper. Dynamic performance of vacuum chamber assembly was first studied. Natural frequencies and vibration modes were analyzed. Then influences of supporting frusta structural parameters on natural frequencies were investigated. And the model of influence was established. Last

the optimization of the supporting frusta structural parameters was carried out and the first natural frequency was improved to 14.44 Hz that satisfied the stability requirement of the ICF facility.
