Chassis dynamometer common failure

Jan 10, 2024

Chassis dynamometer is the key equipment of vehicle performance evaluation, its normal operation is very important to obtain accurate and reliable test results. However, with the increase of use time and the increase of work intensity, the chassis dynamometer may encounter some common faults. This article details these common faults and the corresponding troubleshooting methods to help operators better maintain and manage equipment.
1. The roller is unbalanced
Failure performance: During testing, drum imbalance can lead to inaccurate test results, increased vibration, and even affect equipment life.
Elimination method: Check whether the drum is installed correctly, whether there is foreign matter stuck, and balance adjustment can be made to ensure that the drum remains stable when running.
2. The sensor is faulty
Failure: Sensor failure may result in inaccurate or inaccessible data.
Elimination method: Check whether the connection of the sensor is good and eliminate the problem of loosening or corrosion. If necessary, the faulty sensor can be replaced and calibrated.
3. The power supply is faulty
Fault performance: Power supply problems may cause the chassis dynamometer to fail to start normally or stop suddenly.
Troubleshooting method: Check the power connection to ensure that the power is stable. If there are power fluctuations, consider using a voltage regulator or replacing the power supply.
4. The control system is faulty
Symptom of failure: The failure of the control system may cause the device to fail to respond to the operation and the program cannot run normally.
Troubleshooting method: Check the hardware and software of the control system to ensure that the program is normal. If necessary, contact technical support or update the system.
5. Brake system problem
Failure performance: The failure of the brake system may lead to the failure of the vehicle to stop in time during the test, which has potential safety risks.
Elimination method: Check the brake system regularly to ensure the wear condition of the brake disc and brake pads. If any abnormality is found, replace the parts in time.
6. Data transmission errors occur
Fault performance: Data transmission errors may cause test data loss or incomplete, affecting the accuracy of test results.
Troubleshooting method: Check whether the data cable is firmly connected and confirm that there is no interference source during data transmission. If necessary, you can change the data cable or adjust the transmission Settings.
7. Environmental factors
Failure performance: Harsh environmental conditions can cause the chassis dynamometer to degrade performance and even damage key components.
Troubleshooting Method: Ensure that the working environment of the device is well ventilated to avoid the influence of high temperature, humidity, and dust on the device. Clean equipment surfaces and ventilation systems regularly.
Chassis dynamometer is the core tool of vehicle performance evaluation, its normal operation is very important to obtain accurate and reliable test data. In the face of common faults, the operator should have a certain troubleshooting ability. Regular maintenance and timely fault handling can ensure the stable operation of the chassis dynamometer, extend the life of the equipment and improve the test efficiency.
