A finite element method based on B-spline wavelet was proposed aiming at the oscillation occuring in the numerical solution of high gradient temperature field by the traditional finite element method.A wavelet-based element was constructed,whose shape function was built by the scaling functions of 4th order B-spline tensor product.The finite element mode for the temperature field of clutches in the wavelet coefficient space was built with the Galerkin method based on the axisymmetric heat conduction equations of clutches in the engagement.The transformation from wavelet coefficient space to physics space was studied.The numerical example of the temperature field of clutches in an armored car was presented.Results show that the oscillation was reduced greatly and the precision was improved in the analysis of high gradient temperature field by B-spline wavelet finite element method,which provided an effective approach to improve the clutch design and the engagement control.
