����The mathematic model of predicting the horizontal load subjected to aeroplane undercarriage tyre based on the drop-tests was built by analyzing dynamic loads acting on drop-test platform which is supported by three-poles, and the coefficients in the mathematic model were determined by means of the least-square method according to the results of static tests. Then the horizontal load to aeroplane undercarriage tyre can be obtained more accurately by making use of the proposed model and results of drop-test simultaneously. The practical usesof the proposed method shows that it is more reasonable and more reliable than the method used in former Russia.
