To reduce the effect of impact load on the charge machinery and instrument of vehicle weapon,the composite structure mainly consisting of aluminum-foam was designed according to the damping characteristics of aluminum-foam.The weaking interbedded loads of composite structure and acceleration were measured by using sensor under the conditions of force-hammer experiment.By comparing with simulation results,the feasibility of PVDF and realiability of such results were verified.Based on experimental results,the composite structure of aluminum-foam was obtained,which was applied in noise-reduction and vibration-reduction of precise instrument and meter.The experimental results indicate that the composite structure with this dynamic char-acteristics can be utilized as mechanical filter.
