The landing gear of an aircraft with: mass of 2000 kg the spring-mass-damper system Consider that the runway surface is y(t) = 0.2 cos 157.08t stiffness of the spring is 5 x 105 N/m. What is the suitable damper to limit the amplitude of vibration to 0.1 m. Evaluate if this aircraft can land on a runway with harmonic surface bumps that are 0.3 m in height at a frequency of 200 rad/s. (Aircraft fail if 60% vibration transmitted through landing gear) y(t) x(1) 00000 m ê Wheel- Runway Housing with strut and viscous damping Mass of aircraft, m
