Vibration and noise (NVH) diagnostic program

It is a major challenge for maintenance technicians to reproduce and locate the faults of occasional noises (e.g. squeaks when passing over bumpy road surfaces) and continuous/periodic noises at a particular speed/revving speed during the driving process of a vehicle. The traditional test method is to use a chassis stethoscope, while the vehicle is running on the road, the technician operates the stethoscope to determine and analyze the faults; with this test method, the data is not visualized, cannot be saved and replayed, and analyzing the faults in a speeding vehicle also increases the safety risk.

Vibration and noise (NVH) analysis

The NVH solution provided by Honghong Pico effectively solves these problems. All we need to do is to reproduce the fault, Pico's NVH equipment records the fault data, and the technician returns to the office to analyze it in detail, the data can be replayed, and the sound signals can be replayed as well; the data allows the fault to be “seen”, and ensures the safety of the technician. The data allows the fault to be "seen" and ensures the safety of the technician.

Product Function

Based on vehicle speed/revolution and transmission ratio, the software automatically and accurately isolates vibration or noise sources associated with tires, wheel components, transmission systems, and electrical components. (Stage Analysis)

When collecting data, the moment of failure is marked so that when the data is analyzed later, it is clear which section of the data is faulty.

Long-term monitoring and storage of faulty data; data is replayed to the customer to confirm the faulty sound for analysis.

Remote data transmission is shared, and engineers at the host factory headquarters can analyze the data by simply installing the free NVH software, realizing remote technical support.

Provides high-pass, low-pass, band-pass, and band-resistance filtering to identify faulty sounds in noisy background noise.

The recording file of the third device can be loaded into the NVH software for data analysis. Even if the technician cannot reproduce the fault, it allows the owner to record the sound when the noise occurs in daily driving and send the file to the technician for analysis, thus improving the efficiency.

Analogous to the occurrence of a specific frequency of sound, it is possible to locate resonance response components or check the sealing of doors and windows in the workshop. No need to drive the vehicle on the road to reproduce the fault and then find the fault, saving time.

Accurately recognizes the transmission path of the noise and the sequence of signal occurrence with nanosecond resolution. Especially suitable for identifying which component has failed when there are several components in a small area.

Vibration and noise (NVH) package

Here you can find information about our automotive NVH testing products. Honghong Pico's NVH tester can capture all the vibration and noise amplitude of a car, obtain objective waveforms and data, and compare them with the data collected from the same car model to diagnose the source of the malfunction.

Optical Sensor (Drive Shaft Balancing) Kit

Here you can find information about our products for balancing and testing of transmission shafts. The kit is mainly used for balancing of drive shafts (drive axes), but also supports frequency measurements of other rotating parts. With this package, you can do drive shaft balancing directly on the vehicle without disassembling the drive shaft.
