摘要
[摘要]给出了一种陀螺仪转子悬浮结构.建立了悬浮磁场 B 样条小波有限元模型;研究了一类新的有限元空间.它以 B 样条小波函数作为正四面体有限等参元的形状函数。利用 B 样条小波函数的变尺度特性在不改变网格的剖分下提高分辨率。最后对悬浮系统模型进行了仿真,给出了磁力线的走向、分布及空间各点的磁场强度,并对结果进行了分析。
A supported framework of gyroscope's rotor is designed and the B-Spline wavelet finite element model of sup- ported magnetic field is worked out.A new finite element space is studied.in which the scaling function of B-spline wavelet are consider as the shape function of tetrahedron.The resolution is improved via the varying gradient of the B- spline function under the condition of unchanging gridding.The result is more practical.Plots of flux and in the space is studied via simulating the supported system model.The results of study is useful to the research of the supported mag- netic system for Gyroscope rotor.
