The Stiffness Characteristic Analysis of Negative Stiffness Structure

With the development of technology of vibration isolation,the negative stiffness structure is more widely used in the design of low frequency vibration isolation problem and the computation of negative stiffness is an important problem in the design.A typical structure is analyzed by combining positive stiffness spring and negative stiffness structure.Theory studies show that the finite element method is more efficient.This method can be applicable to compute the stiffness of complicated shape structure in the engineering design.
