The Application of Pseudo-Excitation Method to the Ride Comfort Research of Wheel-Loader
The wheel-loader is modeled as a linear 12-DOF system in this paper for researching its ride comfort under typical working situations. The pseudo-excitation method is introduced for vibration analysis, which accuracy has been validated. By using this method and taking a certain type of wheel-loader as a representative example, the spectral density of real response of wheel-loader such as the vertical acceleration of driver, the for-and-aft angular acceleration of bucket and the wheel relative dynamic force due to different carrying capacity, speed and the road surface level are obtained. The results offer the theoretical evidence for the farther wheel-loader vibration reduction research.
