What is the best way for modeling the random road input in Simulink and how can we get the PSD logarithmic performance of both of road input and vehicle performance (Best PSD Function)?

Can anyone upload an example Simulink for the random input and the PSD Function well.

Qing Wu

In railway, we have formula for PSD (based on space frequency). Using FFT and IFFT (many other methods, i think this is the best) then you can get the random input. i believe road people use similar approaches.
