Working Principle and Using of Chassis Dynamometer |
| |
| Abstract: | Chassis dynamometer with its convenient,safety and good traceability is widely used in automotive development and test.Using data acquisition card driving force and speed measuring is achieved,with communication of MCU and PC sensor signal collection and data transmit is reached.Using chassis dynamometer the output power of driving wheel is measured and converted to engine power.The reason of insufficient out put power of the driving wheel is analyzed and the technical status of the chassis is gained.Chassis dynamometer can be used in simulating resistance force in actual driving,using performance determination,testing auto technical status and diagnosing auto failure. |
