Abstract:

A feasibility study of using a hydraulic vibration machine in conjunction with a drop tower to evaluate ride quality characteristics of a landing gear was made. For sinusoidal inputs over a frequency-double amplitude range of 1-5 Hz and 0.6 to 1.0 inches, amplitude-ratio frequency response of the drop jig was measured. This was done while varying strut pneumatic stiffness and strut friction. This work definitely shows feasibility of a laboratory experimental setup to test ride quality effectiveness of a landing gear.
