Abstract
Abstract
The Jinping neutrino experiment is designed to have multiple
purposes in the China Jinping Underground Laboratory. Following the
acrylic vessel design requirements proposal, a structural scheme has
been developed and optimized. Subsequently, the stability of the
acrylic shell structure is calculated using finite element
analysis, as well as the load-bearing capacities under various
working conditions. Further, the effects of temperature changes,
rope failures, and Young's modulus of the ropes on the static
behavior of the structure are analyzed. The results indicated that
the stress level and structural displacement of the structure scheme
satisfy the design requirements, as well as the stability of the
vessel under compression. The acrylic vessel is safe in the given
working conditions. Temperature is not a controlling factor in
structural design. The structural scheme ensures basic safety if one
vertical rope, two vertical ropes, or one horizontal rope fails.
