| Abstract: | Dynamic model of a metal plate spring vibration isolator system was built up.The friction force curve was calculated using finite element method.Through calculating the dynamic equation,the responses of the system under different harmonic exciting forces and impacts were studied.The results indicated that when an electronic cabinet is placed on the isolator,the system maximum acceleration reduces by 72%;the metal plate spring vibration isolator has good vibration damping and impact-resistance performance.Th... |
