CLIMATIC TEST MODULE
Today’s vehicles are expected to perform reliably to specification in the extreme range of conditions experienced across the world, from sub-zero weather conditions in Antarctica to the humid heat of the tropical rain forests, including high altitude and turbulent/laminar windage conditions.
It is essential during a vehicle development program that the vehicle is tested in facilities that can simulate every kind of driving conditions.
TeSys has a range of special chassis dynamometers, under such operating conditions in Climatic, Altitude and Wind Tunnel chambers/facilities, to provide accurate and repeatable road load simulation, speed, force, and acceleration control modes.
Variable speed cooling fans can also be provided to reproduce the required air-flow simulation.
CLIMATIC, ALTITUDE & WIND TUNNELS CHASSIS DYNAMOMETER
TeSys chassis dynamometers for Climatic, Altitude, and Wind Tunnel testing are all available as standard in single roller, 4×2, 4×4, multi-axles and independent configurations.
The precisely manufactured rollers are available from 0.5m to 2.5m in diameter, running in rolling element bearings which are temperature controlled according to the application. Roller assemblies can be coated to increase the friction coefficients of tyres.
Trunnion mounted AC motors which compensate for system losses and simulate road load forces, vehicle inertia and gradient are mounted on the dynamometer base frame. Thermally insulated floor plates and roller covers protect the motors from extremes of temperature.
The dynamometer base frame can be mounted on a moving carriage to provide wheelbase adjustment to accommodate different vehicles. Roller centers can be set automatically as part of the road load model information or set to the user’s specific dimensions.
The dynamometer is provided with a real-time control processor, control I/O architecture and a GUI with the latest Windows™ Operating System. A powerful data logger can store system and vehicle parameters. A real-time graphics package can display this information on the screen.
A central server function and host computer interface are available to enable data to be passed through in either direction.
