Abstract

This paper proposed the method and model to solve the issue of wheel-soil interaction on the soil runway and attained the equipment for measuring wheel-soil interaction and structural response by improving the design. Furthermore, through field tests, the research results show the characteristics of the three-direction force of the wheel on the soil runway under different tire loads and tire pressures, and present the mechanical response law of the soil runway structure under different soil strengths. In particular, it is found that the rolling resistance and rolling resistance coefficient of the wheel on the soil runway. Finally, the validity of the field test results is verified. This research lays a critical foundation for field testing on the load of aircraft and the formulation of a sophisticated wheel-soil interaction model, which has significant prospects for the structural design, the evaluation of the performance and life of soil runways.
