Overview
When the vehicle continues to operate on the dynamometer, the thermal attenuation phenomenon causes the eddy current motor of the dynamometer to generate heat, resulting in a decrease in its resistance characteristics and ultimately causing the unit current to fail to generate corresponding resistance. To ensure the corresponding resistance is achieved, the dynamometer must increase the current to increase the friction between the drum and the tire.

Dynamic Verification Instrument for Loading Performance of Chassis DynamometerZK-DVLP01
Chassis dynamometer verification device-working principle
When the vehicle continues to operate on the dynamometer, due to the phenomenon of thermal attenuation, the eddy current motor of the dynamometer generates heat during operation, which inevitably leads to a decrease in its resistance characteristics, ultimately resulting in the inability to generate corresponding resistance per unit current. To ensure the corresponding resistance is achieved, the dynamometer must increase the current to increase the friction between the drum and the tire.
Chassis dynamometer verification device-Application scenarios
Suitable for use by ecological environment supervision departments in the supervision and inspection process of emission inspection equipment at motor vehicle testing stations, it can also be installed for a long time at the emission inspection station of motor vehicle testing stations for real-time monitoring and verification of the accuracy of each loading of the chassis dynamometer.
Chassis dynamometer verification device-Product features
1.data collection
The current data is collected using Hall transformers to measure the DC excitation current of the eddy current machine, with a sensor accuracy of one thousandth. The sensor adopts485Serial port access signal acquisition device.
2.Dynamic calibration
The system establishes a dynamic calibration curve through constant force loading method and multiple experiments
3.data labeling
The system is equipped with a data model of the characteristic curve of mainstream chassis dynamometers in China, which reflects the correspondence between the electric current value and torque value of chassis dynamometers.
