摘　　要：通过分析光学元件的动力学响应,计算靶场每条光路的结构漂移误差,进行了靶场结构总体稳定性评估。神光主机装置单光路靶场结构漂移误差计算结果表明:其靶场结构设计满足稳定性要求,该方法可以应用在ICF装置靶场结构总体稳定性设计中,但所得的漂移误差的裕度应大于一个给定的合理值。In order to meet the stringent stability requirement, target area structural systemic stability design was used in the inertial confinement facilities in which National Ignition Facility（NIF）of USA and SG facility are representative. In the structural systemic stability design of the SG facility target area, a new analytical method was proposed to obtain the drifting error of each beam by accounting the dynamic re;ponses of the optical elements. This stability evalutation method was different from that of National Ignition Facility of USA. The calculated drifting errors of the beams indicate that the designed structural system has meet the stability requirement of the SG facility target area. It is concluded that this analytical method can be used in the structural systemic stability design of the inertial confinement facility target area, but the abundance of the obtained drifting error of each beam must be beyond a reasonable given value.
