Abstract:The horizontal tail structure suffers large impact and vibration in landing and taxiing. For predicting the structure local hazard areas, it is necessary to implement an analysis on horizontal tail dynamic performance in landing and taxiing in order to provide a reference for structural strength design. This paper innovatively considered about changes of airplane taxiing rate and the aerodynamic force to provide a reliable set of external input, set reasonable constrains, and established halfbody finite element model of airplane to reduce the size of the calculation. Finally, the peak load response at each horizontal tail station was extracted to generate dynamic response envelope, so the local hazardous positions can be preestimated to provide references for the structure design, such as the root of horizontal tail.
