【Abstract】 Based on the requirement of the I CF drive system project, beam position stability budget is preliminarily evaluat ed by the motion of optical components being related to beam position on target. To adjust as to meet stability requirement, the type B standard uncertainty, ra y-tracing, finite element analyses are applied. Simultaneously based on the str ucture random vibration theory, the optical support structures will be represent ed as a single degree of freedom system with a structural mode, the stability allocations for the different sources of input or excitation can be derived.更多还原
