摘要：
In this paper, the ride comfort obtained from computer simulation was compared to that of physical experiment. To measure ride comfort of a passenger car, acceleration data was obtained from the floor and seat during highway running with different speeds. The measured acceleration components were multiplied by weighting functions, and then summed together to calculate overall ride values. For the computer simulation, MADYMO software was employed. To enhance ride comfort, several air cells are installed in the seat cushion to adjust the stiffness of seat by changing the air pressure in the cells. For the ride comforts, SEAT (Seat Effective Amplitude Transmissibility) was compared. To choose optimum air pressure in the cell, several test drivers with different weights were tested on several vehicle speeds.
