It can be used for automobile loading debugging and diagnosing automobile faults under load conditions; It forms a comprehensive measuring system with five kinds of gas analyzers, transmission opacimeter, engine tachometer and computer automatic control system to measure automobile exhaust emissions under different working conditions.
Chassis dynamometer is easy to use, reliable in performance and not affected by external conditions. Under the premise of not disassembling the car, the service performance of each system and component of the car can be accurately and quickly detected. Chassis dynamometer can be used not only for automobile scientific test, but also for maintenance inspection.
In recent years, due to the rapid development of computer technology and the development and application of various special software, it provides effective means for road simulation, data acquisition, processing and test data analysis, accelerates the development of chassis dynamometer and has been widely used.
Principle:
The chassis dynamometer uses roller simulation to replace the road surface, and all kinds of resistance encountered by the car when driving at a normal uniform speed are simulated by the loading device. When the car is accelerating and taxiing, the resistance is simulated by the moment of inertia of the flywheel group. The torque and power of the chassis dynamometer are measured by the force sensor installed on the force arm, which connects the stator and the dynamometer housing. When the car drives the drum, the loading device applies braking torque to the rotor through the stator, and at the same time, the stator receives the reaction torque of the rotor, which is measured by the force sensor and converted into the torque and power of the driving wheel.
