目的：对600g-t土工离心机的吊篮各部件开展力学分析与强度设计。方法基于土工离心机的吊篮结构初始设计方案，利用Ansys有限元分析软件，采用非线性接触算法开展吊篮优化力学分析。结果通过优化设计，吊篮结构相对于初始结构各部件的最大应力下降39%~59%。结论优化后的吊篮结构满足强度要求。
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.
