Bicycle Car Vibration Model and Body Pitch Mode

The simplest vehicle model to study the pitch mode of vibrations is the bicycle model in which we longitudinally cut a vehicle and take one side to study. Figure 10.1 illustrates a bicycle vibrating model of a vehicle. This model includes the body bounce x, body pitch \(\theta \) , wheels hop \(x_{1}\) and \(x_{2}\) , and the road excitations \(y_{1}\) and \(y_{2}\) .
