| Abstract: |
| Objective To study mechanical behaviors of the suspended basket, especially the strength and stiffness performance under the centrifugal loading. Methods By precisely modelling the contact relations between parts of the basket, the present paper established a finite element model based on an initial design of centrifuge baskets. Special emphasis was placed on a systematic study of the strength property of centrifuge baskets. Calculation and analysis were performed to check the overall structure, the strength of key parts and the reduction of local stress concentration. Results Certain stress concentration existed due to local contact between the lifting lug and the bob-weight, leading to the result that the safety parameters failed to meet requirement on strength. Conclusion An improved design is provided with higher structual strength, which satisfies the corresponding mechanical strength requirements. |
