摘要

为了更好地解决压缩机运行过程中的漏气问题,在收敛阶跃式磁力流体密封结构的基础上,采用l16(4 4)正交试验设计和有限元数值模拟相结合的方法对密封结构进行优化。本文选取了四因素、四水平和相应的正交表。对各试验的仿真结果进行了计算,并对极差值进行了研究。最后对优化前后结构的密封承压能力进行了计算和比较。结果表明:在不同轴向和径向密封间隙条件下,经过正交优化后,收敛阶跃式磁力流体密封结构的密封承压能力得到了显著提高,尤其是在径向密封间隙较小时;最大耐压能力提高约11%,充分证明了正交优化的有效性。同时,研究结果也可为其他回转密封工况的应用提供参考。

Orthogonal Optimization Design and Finite Element Analysis of Converging Stepped Magnetic Fluid Seal
In order to better solve the problem of air leakage during compressor operation, based on the converging stepped magnetic fluid seal structure, the L 16 (4 4 ) orthogonal test design and the numerical simulation of the finite element method are combined to optimize the sealing structure. Four factors, four levels and the corresponding orthogonal table are selected in this paper. The simulation results of each test are calculated and range values are studied. Finally, sealing pressure capability of the structure before and after optimization are calculated and compared. The results show that under the conditions of different axial and radial sealing gaps, the sealing pressure capability of converging stepped magnetic fluid seal structure has been significantly improved after orthogonal optimization, especially when the radial sealing gap is relatively small. The maximum pressure capability can be improved by about 11 %, which fully proves the effectiveness of orthogonal optimization. At the same time, the research results can also provide references for the application of other rotary sealing conditions.
