| 摘要： | This TOP describes methods for evaluating the ride dynamics or ride quality of ground vehicles. Ride dynamics pertains to the sensation or feel of the passengers in the environment of a moving vehicle. The technique for evaluating the ride dynamics involves the use of instrumented seats or ride quality pads which contain accelerometers molded in a rubber disk to provide measurements in three mutually perpendicular axes. The instrumented seats are occupied by the normal vehicle crew. Ride dynamics data is acquired while the vehicle traverses various test courses at pre-determined speeds. The data is then processed by performing Fourier transformations and creating power spectral density (PSD) files for the individual test runs. |
