Stress distribution and stability under extreme conditions of screw-loading device are investigated in the present study. The finite element model of core component is established to obtain the loading process. Influence of screw position on magnitude, distribution, and types of component structure is also investigated. Eccentricity phenomenon of screw-loading device is analyzed, and loading performance under noncoincident central line of moving and rotating disc is obtained. Results showed that transmission force formation of screw groove structure is similar to concentrated force. The transmission force is remarkably different from other positions when marble is on top or bottom of the screw groove. An optimization design based on these results is proposed in this study.
