精密离心机转盘/转臂结构变形规律研究

目的研究不同转盘/转臂结构在离心载荷和温度载荷作用下的变形。方法在充分调研国内外相关研究的基础上,分析几种转盘/转臂给定工程结构在离心载荷和温度载荷作用下的变形规律。结果通过分析可以得到,不同转盘/转臂结构随离心载荷的增大变形增大,随温度的正向变化变形量增大,随温度的负向变化变形量负向减小。结论同等载荷作用下的变形量主要由该种结构形式转盘/转臂材料分布决定。对比几种转盘/转臂结构可以看出,锥形辐射式加强筋转盘综合承载能力较优,可为工程选用。

Variation of Precise Centrifuge Plate/Arm

Objective To study the variation of different plate/arm structures under centrifugal and temperature loads. Methods Based on the study of domestic and overseas literatures, this paper analyzed several kinds of variation patterns of plate/arm structure under the centrifugal load and the temperature load. Results The results showed the variation of different plate/arm structures were enlarged when the centrifugal load increased and the variation was increased along with the positive temperature changing and decreased along with the negative temperature changing. Conclusion Under the same loading, the variation of the plate/arm depends on material distribution. The comparison of several kinds of the structure of the plate/arm shows the comprehensive carrying capacity of the conical ribbed plate is better, and this structure could be used for engineering.
