With the development of aviation,the aircraft hot-refueling technology is adopted to improve maneuverability,which means that the aircraft in the trial flight can break away from braking.But the conventional chocks fail to stop aircraft mov-ing,and they will easily damage the airport ground because of the tire pressure.In this article,in order to solve these problems,a bionic aircraft chock based on the goat hoof is designed.It can decompose the resistance between the chock and the ground,and increase the interaction force between them.The discrete element simulation is applied to optimize the chock's supporting foot,and the multi-body dynamics is used to simulate and compare the bionic chock and the conventional chock.The result shows that compared with the two other conventional counterparts,this bionic chock is desirable in many aspects.Its horizontal resistance on both sides increases by 170％and 81％respectively,and its forward resistance increases by 98％and 70％;the blocking effect significantly improves;the damage to the ground is avoided because of the enlarged contact area between the bionic chock and the ground.
