  • For calculating the stiffness function of a structure,the differential equation of the vibration of the structure was divided into the differential equation on the original stiffness function that was known,and Fredholm integral equation of the first kind on the undetermined stiffness function that was unknown.And the stable solutions of the integral equation,when the smooth factor was equal to zero,was solved by the extrapolation with psmooth factors.So the stiffness function of the structure is obtained.Applied examples show that the method is feasible and effective.
