Abstract EN
When a carrier-based aircraft is in arrested landing on deck, the impact loads on landing gears and airframe are closely related to landing states.
The distribution and extreme values of the landing loads obtained during life-cycle analysis provide an important basis for buffering parameter design and fatigue design.
In this paper, the effect of the multivariate distribution was studied based on military standards and guides.
By establishment of a virtual prototype, the extended Fourier amplitude sensitivity test (EFAST) method is applied on sensitivity analysis of landing variables.
The results show that sinking speed and rolling angle are the main influencing factors on the landing gear’s course load and vertical load; sinking speed, rolling angle, and yawing angle are the main influencing factors on the landing gear’s lateral load; and sinking speed is the main influencing factor on the barycenter overload.
The extreme values of loads show that the typical condition design in the structural strength analysis is safe.
The maximum difference value of the vertical load of the main landing gear is 12.0%.
This research may provide some reference for structure design of landing gears and compilation of load spectrum for carrier-based aircrafts.
