| 中文摘要: |
| 鉴于碟式分离机转鼓缺乏应力计算的成熟方法，以胶乳分离机转鼓为对象，研究了静应力特性，建立了力学模
型，分析了载荷与几何约束，构建了有限元模型，分析比较了关键件不同工况下的应力及分布，分析结果表明：转鼓整体
应力水平分布不均匀性明显，转鼓体沉渣区、侧壁等位置局部应力水平很高，转鼓体最大应力的位置，与转鼓体实际裂纹
失效发生部位相符。建模方法、分析结果对转鼓设计、强度评价、结构优化等具有借鉴价值。 |

| In view of lacking well-developed stress calculation method for rotating drum-assembly of disc-separator, the
simplified drum-assembly of latex separator was taken as research object, and the statics stress characteristics was
studied. Mechanical models of main elements were established by force analysis. Constrained boundary conditions of
Finite element analysis ( FEA) were determined. Analysis model of FEA was set up. Stress characteristics of drum
elements was analyzed under idle status.work status and over speed status. Drum stress distribution regularities were
compared in four working conditions. Study results show that: stress distribution for the overall drum is non-
homogeneous.sediment area and side wall of drum-base have high local stress. Max-stress position of FEA agrees with
experimental crack extending point in the drum-base. FEA modeling method and the results provides important guidance
and reference for drum design, strength assessment and structure optimization. |
