Unformatted text preview: natural frequency?
landing sys For the simplified model of an airplane landing gear system pictured below, show the steps taken and calculations needed to find the damped natural frequency of the system. Hint: Consider that the equation of motion can written as: c
k + x + x = 0 x
m
m 2 + 2ςω n x + ω n x = 0 x Solution: From Example 1.4.1, the undamped equation of motion is Solution: From Example 1.4.1, the undamped equation of motion is! m + J # ˙˙ + kx = 0
