Abstract:
In order to evaluate the ride quality of the soil compactor cab supplemented by the auxiliary hydraulic mounts(AHM), a nonlinear dynamic model of the soil compactor interacting with the off-road deformable terrain is established based on Matlab/Simulink sofware. The power spectral density(PSD)and the weighted root mean square(RMS)of acceleration responses of the vertical driver’s seat, the cab’s pitch and roll angle are chosen as objective functions in low-frequency range. Experimental investigation is also used to verify the accuracy of the model. The influence of the damping coefficients of the AHM on the cab’s ride quality is analyzed, and damping coefficients are then optimized via a genetic algorithm program. The research results show that the cab’s rubber mounts added by the AHM clearly improve the ride quality under various operating conditions. Particularly, with the optimal damping coefficients of the front-end mounts ca1, 2 = 1 500 N·s/m and of the rear-end mounts ca3, 4 =2 335 N·s/m, the weighted RMS values of the driver’s seat, the cab’s pitch and roll angle are reduced by 22.2%, 18.8%, 58.7%, respectively. Under the condition of the vehicle travelling, with the optimal damping coefficients of ca1, 2 = 1 500 N·s/m and ca3, 4 =1 882 N·s/m, the maximum PSD values of the driver’s seat, the cab’s pitch and roll angle are clearly decreased by 36.7%, 54.7% and 50.6% under the condition of the vehicle working.
