Abstract:
Based on seven degree of freedom vibration model of truck, pseudo road excitation is constructed with pseudo-excitation method. System frequency response of vehicle is deduced by pseudo relationship between road excitation and vehicle responses. Pseudo responses of vehicle and pseudo vibration response variables of vehicle are built, and the method of statistical characteristics for real vibration response variables is given by pseudo vibration response variables. The result shows that pseudo-excitation method is better than Fourier method.
