Apply driver and longitudinal inputs within a repeatable and controlled environment to evaluate the efficiency, performance and durability characteristics of a vehicle drive train while operating on a straight, smooth road. Data generated by this system can be used for meeting WLTP (Worldwide-harmonized Light Vehicle Test Procedures) requirements as well as powertrain tuning for traditional ICE or EV applications.
Applications
Consumo de energía
Medición de la pérdida por rodadura del tren de potencia
Medición de inercia
Facilidad de conducción
Ajuste del tren de potencia
Test Specimens
Vehículos de pasajeros y todoterrenos
Camiones ligeros
Test Standards
Procedimiento de prueba armonizado para vehículos ligeros a nivel mundial
MTS Flat-Trac moving belt technology accommodates spinning tires to create a high-fidelity, real-world vehicle-to-road interface.
Accurate / Repeatable Results
Provides the vehicle-to-road interface accuracy needed to discern extremely fine changes in rolling loss from one design iteration to the next
Efficient Operation
Far more accommodating of high-throughput testing requirements than conventional roller dyno solutions
Versatile
Accommodates any vehicle by varying track width, wheelbase, type of positioning, power density and bearing type

The longitudinal restraint portion of the 3-Link Restraint is adjustable with either soft and rigid mounting. The soft mounting allows limited body motion during accelerations and decelerations to allow the driver to sense tuning results of the vehicle control unit. Range of motion of the longitudinal restraint is limited by the air bearing range in the tire input assemblies.
