A Study of Road Load Severity Prediction in Market for Power Spectrum Density

When we develop the new car, the conditions under which vehicles are used in the market is an important factor in assuring vehicle durability. Because of Asia and Oceania etc. that will increase number of the car has much gravel road(The cruel areas), calculating the severity of road load is most important factor. In this work, we show you simple measurement and analytical method for the severity of road load in the cruel areas, that use the principle of road power spectrum.
