Research on Development of Vehicle Chassis Dynamometer

Vehicle chassis dynamometer, as an important part of vehicle test equipment, plays an important role in the research and development of the vehicle's entire life cycle. The development history of vehicle chassis dynamometer from hydraulic dynamometer to AC dynamometer was reviewed, and it was proposed that AC chassis dynamometer has become the mainstream trend. The vehicle chassis dynamometer was further discussed from the aspects of measurement and control system and road simulation system. On the basis of the current research status of dynamometers, based on the virtual test technology, network, intelligence and function expansion, the development direction and research focus of vehicle chassis dynamometers are given to provide reference for the further development of vehicle chassis dynamometers.
