I'm trying to generate a random road which will be used as input for a Quarter-car model.
I used the procedure described in this article http://link.springer.com/article/10.1007%2Fs12544-013-0127-8/fulltext.html .
In Figure 2, generated roads are plotted with a maximum elevation of 15 mm for A-B category and 100 mm for D-E. My problem is that I get much higher amplitudes from those reported by them. I attached the code that I'm currently using. I'm not sure what I'm doing wrong, any guidance would be appreciated.
Length of road = 250 meters
Spatial frequency band = 0.004 -> 4
Here are some formula used to generate road.

This is a strange thread: 4 persons posted their email address, which this unusual in a public forum. One has posted a new question in the section for answers, which I have removed.
