 Consider the base-excitation problem of Section 2.4 as applied to an automobile model of Example 2.4.2 and illustrated in Figure 2.17. Recall that the model is a spring–mass– damper system with values m = 1007 kg, c = 2000 kg/s, k = 40,000 N/m. In this problem let the road have a random stationary cross section producing a PSD of S0 . Calculate the PSD of the response and the mean-square value of the response.
Example 2.4.2
A common example of base motion is the single-degree-of-freedom model of an automobile driving over a road or an airplane taxiing over a runway, indicated in Figure 2.17. The road (or runway) surface is approximated as sinusoidal in cross section providing a base motion displacement of y
