AIuminium honeycomb composite material is a new material which has the advantages of high strength of the structure. Basic. mechanical properties of aluminium honeyeomb composite material used inDus-platfurm whieh contained stretching, compression, and peel strength were tested respectively. The test results show that the aluminium honeycomb bus platform is better than other bus plaffomn materials in mechanical pruperties. Modal parameters anti physical parameters were analyzed based on modal analysis theoL＇y. The dynamie elastic modulus of aluminium honeycomb and the static elastic modulus based on three point bending method were compared and analyzed. Data results show that the dynamic elastic modulus is generally higher than static elastic modulus, and can be used as a kind of assessment index of aluminium boney- comb eomposite material. Finally, the research achievements were summarized and the further researching direetions were prolapsed.
