Title:Inertia Calculation for Single-Ended Inertia-Dynamometer Testing
Issuing Committee:Brake Dynamometer Standards Committee
Scope:This Recommended Practice is useful to determine the inertia value (wheel load and tire radius) using three basic methods (fixed brake work split, dynamic weight transfer, and axle rating) to determine the wheel load and two methods to determine the tire radius (SLR and rolling radius). The inertia values are required to determine the amount of energy and brake work imposed on the brake during testing. The inertia level (mechanical or simulated) is required also to calculate deceleration levels from a given torque value or the torque level for a given deceleration value or set-point. This procedure is applicable to all passenger cars and light trucks up to 4,540kg of GVWR.【英文标准名称】:Protectiveclothingforuseagainstsolidparticulates--Part2:Testmethodofdeterminationofinwardleakageofaerosolsoffineparticlesintosuits
