| Abstract: | The thesis adopted the mode of "cantalever grider" freeness end,mensurated dynamic elasticity model and damp ratio of HDF and OSB test materials.For illuminate correctness of the dynamic testing method,the paper showed static elasticity model results of HDF and OSB test materials.The results showed that its dynamic elasticity model and static elasticity model complexions were consistent.It incarnated the dynamic testing merits on speediness,convenience and good repetition etc. |
