Model 6900 Commercial Vehicle Brake Dynamometer


The full-sized Model 6900 Commercial Vehicle Brake Dynamometer is robustly designed for performance and durability testing of brakes for off-highway and commercial vehicles. A multi-disc inertia section, combined with electric motor Inertia Simulation (I-Sim), replicates test conditions for a wide range of vehicles. It is qualified for research and development of air and hydraulically actuated drum and disc brakes, as well as, friction materials. The system can be configured for single or dual-end operation, with clutched inertia discs, a static torque system, environmental conditioning, noise insulation, water spray and dust spray. A noise, vibration & harshness (NVH) analyzer, disc thickness variation (DTV) measurement, full wheel fixture, stainless steel test enclosure, video camera and thermal imaging system are also available.
