BorgWarner Automotive (BWA) pursued a vision to develop an encompassing electric test cell capable of simulating the full vehicle environment. The BWA test system described in the paper will accommodate full transmission installations as well as any selected component or subsystem. By simulating the vehicle environment, many known powertrain development constraints can be overcome. A test cell that can simulate the characteristics of an internal combustion engine, vehicle drivetrain characteristics and road load is required. BorgWarner decided to push the existing test capability envelope and selected partners to develop the technologies to accomplish this task. The process started in 1995 and has led to an existing installation in the Advance Product Engineering Test Labs in Sterling Heights, MI. Furthermore, an enhanced technological variant: a second-generation machine is currently under construction and will be delivered early in the first quarter of the year 2000. Many test machine builders are making claims of providing highly dynamic systems, i.e., the use of low inertia, high response motor/drive combinations. The BWA system is based on a similar claim and demonstrates the use of electric motors to simulate a firing combustion engine. But the facility goes further, by providing a full and configurable development environment. The BWA machine design intent was focused on transmission related development, but it does not preclude the use of this technology in other test applications.The capabilities to simulate vehicle inertias, resonances and more importantly engine combustion torsionals, will allow development engineers the opportunity to screen and develop transmission systems while exploring the characteristics of NVH in a controlled laboratory environment.
