Using ADAMS to Assess Dynamic Load of Pavement during Aircraft Landing

In order to provide a rational dynamic load coefficient for airport rigid pavement design and reduce the workload of the pavement dynamic load test, the software ADAMS was used to analyze the dynamic response mechanisms of the vertical load, longitudinal load, and lateral load on the pavement. The loading sensitivity of the pavement was analyzed by independently varying pitch angle, roll angle, initial descending rate, and initial ground clearance. In addition, different roughness levels of pavements were generated by the white noise linear filtering method to study the effect of roughness level on the dynamic load response of pavements. The results show that when the initial descending speed increases from 0 to 3 m/s, the dynamic load coefficient increases from 0.677 to 1.623; the horizontal load during aircraft landing is mainly in the longitudinal direction; and the peak value of aircraft dynamic load on level H pavement increases 68.71% than level A pavement.
