English term or phrase: quarter-car model
ASTM E1926 defines the standard procedure for computing the IRI from longitudinal profile measurements based upon a mathematical model referred to as a quarter-car model. The quarter-car is moved along the longitudinal profile at a simulation speed of 80 km/h and the suspension deflection is calculated using the measured profile displacement and standard car structure parameters. The total absolute value of the simulated suspension vertical oscillation is then divided by distance travelled to give an index with the unit of a slope (mm/m), which is named as IRI.

The quarter-car model used in the IRI algorithm is just what its name implies: a model of one wheel (a quarter) of a car. The model is shown schematically in Слика-8 below. Device includes one tire, represented with a vertical spring, the mass of the axle supported by the tire, a suspension made of a spring and a damper, and the mass of the body supported by the suspension for that tire. The quarter-car simulation is meant to be a theoretical representation of the response-type systems used at the time the IRI was developed.

модел за испитување на динамиката на возилото

Станува збор за еден од најкористените модели за испитување на динамиката на суспензијата на возилата.

Често се остава на англиски: „модел quarter-car“, но сметам дека описното решение е поприфатливо.
