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.
