Abstract：The relationship between stiffness of isolators and vibration frequency is deduced according to testing result of rubber’s Young's modulus and stiffness, and isolators’ static stiffness and dynamic stiffness are used to determine relevant coefficients. Stiffness dispersion is brought into theoretical estimation of rubber isolators based on four-polar parameter equations for higher accuracy.On the other side, an impedance testing method based only on acceleration measurement is designed and two types of rubber isolators are tested in this method. By the comparison of testing results and estimation results under different stiffness modes, it is concluded that impedance estimation is more accurate with stiffness dispersion considered and the test based on acceleration is feasible.
