ASTM-E2034 › Standard Practices for Simulating Truck Response to Longitudinal Profiles of Vehicular Traveled Surfaces
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 These practices cover the calculation of truck response to longitudinal profiles of traveled surface roughness.
1.2 These practices utilize computer simulations to obtain two truck responses including: sprung and unsprung mass vertical displacement, velocity and acceleration, and sprung mass pitch angular displacement, velocity, and acceleration.
1.3 These practices present standard truck simulations (quarter truck, half-single unit truck, and half-tractor semitrailer) 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.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Significance and Use
5.1 These practices provide a means for evaluating truck ride quality and pavement loading exerted by truck tires.
ICS Number Code 35.240.60 (IT applications in transport and trade); 43.040.01 (Road vehicle systems in general)
