Dynamic Analysis and Seat Selection of Bus Driving Comfort under Different Road Conditions

The comfort of a bus running on different road conditions is matter public concern. In this paper, the differential equations motion are established for and whole driving process mechanically analyzed. Firstly, bump degree at positions quantitatively analyzed it found that rear row bumpier roads. Then, relationship between speed vertical displacement acceleration described. Regardless speed, similar will be eventually achieved, but higher, duration maximum longer. When 8 m/s, resonance occurs during condition II. Finally, change in under action spring stiffness coefficient ratios front wheels High mean less acceleration. By establishing an actual excitation surface, analytical solutions paper can used to roughly analyze mechanical response traveling bus. These results provide some guidance design buses.
