J2264 - Chassis Dynamometer Simulation of Road Load Using Coastdown Techniques

Details Not available for purchase at this time. Document Number: J2264 Project Initiation: 11-06-2007 Sponsor Name: Jeff Glodich Title Chassis Dynamometer Simulation of Road Load Using Coastdown Techniques Scope This procedure covers two-wheel drive vehicle operation and single-axle electric dynamometer load coefficient adjustment to simulate track road load within the speed range of track testing and the dynamometer inertia and road load simulation capabilities. The purpose is to provide a uniform procedure for adjusting an electric chassis roll dynamometer to provide accurate simulation of the resistance which must be overcome by the vehicle powertrain to maintain steady speed on a flat road, as determined by track coastdown tests on that vehicle.
