Abstract

The main structure of “Shenguang-III” (SG-III) target system is of a reinforced concrete steelwork integral, including a classification station and a diagnostic physics lab which are separated by a wall between them. The six floors of the diagnostic physics lab are connected and supported by several poles of reinforced concrete and hundreds lens and reflecting mirrors are distributed on them. A vacuum target room lies at the center of diagnostic physics lab and is fixed on the ground by a pole and linked to the floors by beams. So the rotational angles of the lens and reflecting mirrors may influence shooting precision of the SG-III system. By finite element method, the rotational angles of the optical frames fixing the lens and reflecting mirrors were analyzed on condition that the base of the diagnostic physics lab is subjected to a certain load of power spectral density. The results supply dynamic suggestions to redesign the target zone structure and backstop lens frame of the SG-III laser facility.
