The restraint failure of airplane wheel chocks is one of the most important reasons for accidental airplane movements and the ground accidents in civil aviation. The calculation formula of wind lift force on airplanes is set up according to the running time-speed-load test data of a B737-800 on the ground. The finite element mechanical radial tire model is set up based on the Mooney-Rivlin constructive model according to the outline deformation test data of airplane tires under different loads. The restraint efficacy and failure modes of statically indeterminate chocks are studied by ANSYS based on the chocks' working conditions, and the new parameter of pushing coefficient is put forward to evaluate the restraint efficacy. In the end, an optimized design scheme is presented for B737-800 metal chocks. The numerical analysis shows that the optimized chock can better match the airplane tires under different loads and can exert more restraint efficacy.
