Product Code:SAE J2181
Title:Steady-State Circular Test Procedure for Trucks and Buses (STABILIZED Sep 2011)
Issuing Committee:Truck And Bus Total Vehicle Steering Committee
Scope:This test procedure is used to determine the steady-state directional control response of vehicles by measuring steady-state cornering behavior. Due to the wide range of operational conditions to which a vehicle can be subjected, the results of this testing do not provide a complete description of a vehicle's total dynamic behavior; in particular, the procedure does not test the vehicle's response during transient maneuvers. To fully assess a vehicle's total dynamic behavior, it would be necessary to conduct other test procedures in order to evaluate the vehicle's performance as a whole.The extent of instrumentation and the required accuracy of the measurement will be dependent on the goals of the personnel conducting the test. If it is desired simply to determine the general performance characteristics of a vehicle, then this test can be conducted with minimal instrumentation and test item preparation.This SAE Recommended Practice establishes a uniform procedure for determining the steady-state directional control response of trucks, buses, and combination vehicles.
