Langley Research Center has developed a portable, self contained ride quality meter for accessing ride quality during vehicle operation. System is applicable to air, sea, road, or track vehicles for estimating passenger ride comfort in the presence of complex vibrations and interior noise. Meter has three components: a package of three vibration sensors, a microphone, and a computer. Installed on the floor of the vehicle being tested, sensors measure vibrations in five different axes, microphone measures noise level, and computer processes input from both and gives user a printed readout including a number of options for assessing ride quality.
