Title: Modal analysis of IMU structure based on B-spline wavelet finite element
Abstract: A framework of inertial measurement unit is designed and the B-spline wavelet finite element model of IMU is worked out.A new finite element space is studied in which the scaling function of B-spline wavelet is considered 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.So there are some advantages in dealing with the focus force and a high varying gradient,and its result is more close to practical.Finally,simulation results verify the proposed model and give the modal value of every order.Compared with the traditional FEM,the wavelet FEM has good astringency,the agile ability of grid partition and the feature to solve problems fast.
