The NVH Test Stand is designed for automotive motors.

It is used in production lines to test automotive motors and to identify defective products through various analysis modes (e.g. time domain analysis, order analysis, bearing failure diagnosis, etc.). The software stores test records and can output reports, spectrogram and time domain diagrams. The tests can be used to determine whether the product meets production standards. The analysis data can be used to improve the performance, quality and life of the motor, thus enhancing the comfort of the vehicle.

NVH test stand design features

• Floor vibration isolation
• Transmission chain vibration isolation
• Electromagnetic interference and electromagnetic vibration isolation
• Automatically controlled test procedures

Customized mounting and fixing fixtures are available to suit the customer's product, combined with automated vibration sensors for NVH analysis, judgment and documentation.
