About: D-value (transport)

An Entity of Type: Thing, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

In transport, D-value is a rating in kN that is typically attributed to mechanical couplings, and reflects dynamic loading limits between a towing vehicle and a trailer. The corresponding formula for a truck and trailer combination, used to determine the required D-value of a coupling, is: T = Weight of towing vehicle including the vertical load on the fifth wheelR = Total weight of the loaded semi-trailerU = Vertical load on the fifth wheelg = Acceleration due to gravity (assumed to be 9.81 m/s 2 ) D (kN) = g x ((0.6 x T x R)/(T + R - U))
