Significance and Use
4.1 These practices provide a means for evaluating traveled surface-roughness characteristics directly from a measured profile. The calculated values represent vehicular response to traveled surface roughness.
4.2 These practices provide a means of calibrating response-type road-roughness measuring equipment.
1.1 These practices cover the calculation of vehicular response to longitudinal profiles of traveled surface roughness.
1.2 These practices utilize computer simulations to obtain two vehicle responses: (1) axle-body (sprung mass) motion or (2) body (sprung mass) acceleration, as a function of time or distance.
1.3 These practices present standard vehicle simulations (quarter, half, and full car) for use in the calculations.
1.4 The values stated in SI units are to be regarded as the standard.
1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
