Other Applications
Applications to road vehicles have been attempted, and Fig. 2 showed good results for the RMS of the side force and pitching moment. As an extension
of the theory, we have tried to simulate the gust response of a SUV (Range Rover), as shown in Fig. 6.
2. Conclusions
A theory for the simulation of small perturbation potential fbws under sinusoidal gust conditions has been derived and applied via the strip theory to

a number of analytical and generic two-dimensional plates. The analysis was carried out in the frequency domain. An extension of the theory can be done as to include road vehicles (cars and high speed trains), and neglecting secondary effects in the third dimension. Results obtained for these bodies are reasonable and compare well with existing experimental data. The model does not allow for the simulation of yawed fbw conditions and for the effects of turbulence.
Possibilities exist to extend the theory to calculate the drag response in the frequency domain, and to treat systems with more than one degree-of-freedom.
