- Abstract
In order to evaluate the performance of semi-active cab's hydraulic mounts(SHM)of the off-road vibratory roller with the optimal fuzzy-PID(proportional integral derivative)control, a nonlinear dynamic model of the vehicle interacting with off-road terrains is established based on Matlab/Simulink software. The weighted root-mean-square(RMS)acceleration responses of the driver's seat heave and the cab's pitch angle are chosen as objective functions. The SHM is then optimized and analyzed via the optimal fuzzy-PID control under different operation conditions. The simulations results show that the driver's ride comfort and the cab shaking are greatly affected by the off-road terrains under various operating conditions of the vehicle, especially at the speed from 8 to 12 km/h on a very poor terrain surface of Grenville soil ground under the vehicle travelling. With SHM using the optimal fuzzy-PID control, the driver's ride comfort and the cab shaking are clearly improved under various operation conditions of the vehicle, particularly at the speed from 6 to 7 km/h of the vehicle traveling.
