Abstract

Abstract

In order to obtain the plexiglass ball structural scheme suitable for the Jinping Neutrino Detector， four plexiglass balls and the corresponding supporting schemes were proposed. The maximum stresses on the balls， axial forces of ropes， and structural displacements of the proposed schemes were compared. The load-bearing analysis of the optimized scheme in various working conditions were performed. The results showed that the stress on the ball for Scheme Ⅱ was the largest， and Scheme Ⅳ was the best scheme. In normal working condition， the maximum Mises stress on the plexiglass ball of Scheme Ⅳ was 2.57 MPa， the maximum first principal stress was 2.23 MPa， the maximum axial force of the ropes was 121 kN， and the maximum structural displacement was 182 mm. In the worst working condition， the maximum Mises stress of Scheme Ⅳ was 3.81 MPa， the maximum first principal stress was 4.54 MPa， the maximum cable axial force was 122 kN， and the maximum structural displacement was 184 mm， which could meet the requirements for the bearing capacity.
