A New Measurement Method for Quantifying the Ride Comfort

There has not been any quantitative measurement method for the vibrational ride comfort in the world. All the previous methods for measuring it have been using the acceleration sensors (accelerometers) and therefore have not examined the medical aspect of the ride comfort. I invented a new measurement method for quantifying the ride comfort using the artificial human model that includes artificial human lumbar model, and I took the pressure variation at the artificial nucleus pulposus, did experiments about the pressure variation curves on highway bridge joints at various speeds. The results are satisfactory. The static characteristics are quite linear, and reproducibility of the pressure wave is within about 10%.
