ABSTRACT:Objective To carry out the mechanical analysis and strength design of the nacelle on the 600g-t geotechnical centrifuge. Methods Referring to the original designs of the nacelle on the centrifuge, non-linear contact analyses were carried out on the nacelle of the 600g-t centrifuge by utilizing the contact algorithm in the software ANSYS, and optimizations of the mechanical behaviors of each part of the nacelle were done accordingly. Results FEM results revealed that the maximum von Mises stress of the each part of the nacelle was reduced by 39%~59%after optimization compared to the initial values. Conclusion Optimized structure of the nacelle satisfied the strength requirements.
