Abstract:Based on the dynamic model of a nonlinear dry friction system,combining with the strong geometric nonlinear mechanical charactristics of mental friction plates, the calculation formula for acceleration response of a dry friction isolator under larger impact load was derived by using the piecewise Duhame integral method.The theoretical calculation results were compared with test ones of pendulum to simulate large impact.It was shown that the proposed method can better reflect motion laws of a metal dry friction isolator under larger impact.
