Testing that Reaches the World
Propulsion System Simulation and Testing
Clark Testing’s Propulsion Dynamics Laboratory (PDL) provides system simulation for transportation and transit vehicles prior to field-testing or deployment. The lab fully integrates propulsion, braking, resistance and control systems, reproducing the environmental conditions a vehicle will encounter in the field.
The propulsion lab can simulate acceleration, deceleration, braking, dwell time along with a number of dynamics and static profiles as designated by field data acquisition. The power distribution system feeds a rack mounted propulsion system connected to the drive and resistance motors through an underground channel.
The entire system is operated with a proprietary software control system from our control room located above the laboratory. A 60’ racking system is used to simulate the installation of the components on the transit or mobile vehicle, as they will be mounted in the vehicle. The propulsion lab is modular and flexible allowing us to conduct direct drive motor testing for electric vehicles.
