Design and analyze on an open and close rapidly cryogenic thermal shroud
Abstract:For the requirement of cryogenic target's instant exposure before shooting in the inertial confinement fusion,a kind of rapidly retractable shield structure is designed .Motion mechanism design,parameter calculation and structural modelling of the shield along with the numerical simulation of the driving mechanism's motion curve and motion parameters have been done in this paper.The calculation results show that the motion mechanism of the designed shield which can open and close in an angle of 62.09 within 50ms and whose movement velocity is smooth without impact meets the experimental requirements.
Keywords: cryogenic thermal shroud structural design numerical simulation ICF
