Noise, Vibration & Harshness (NVH) Kits
Customer complaints about noises and vibrations are subjective and present a huge challenge. Pico’s range of Noise Vibration and Harshness (NVH) Kits provide the answer in that they offer an objective diagnostic record and analysis of vibrations and noises.
Please click here for our VAS NVH Kit.
- Cabin vibrations at speed
- Engine vibrations throughout the entire RPM range
- Clutch judder or vibration
- Transmission and bearing whine
- Auxiliary drive noise
- Brake judder
- Steering vibrations
Once you have an NVH system, you will be able to demonstrate the problem to your customers as well as the quantify the effectiveness of the repair, objectively. See our new NVH Training Course - now available in South Africa.
Example – Broken Coil Spring
The example image below shows the Pico Diagnostics screen recording of a broken suspension coil spring in a Volkswagen Golf. (T1 means Tyre, first order vibrations, i.e. once per revolution).
Kit Overview
The Kits include accelerometers (vibration) and microphones (sound) and recording takes place whilst test driving the vehicle. The recording process is automatic so the driver’s attention is not diverted from the road and the results can be analysed in the workshop afterwards.
Software Overview
The software provides a real-time diagnosis to the technician, in the form of either: a bar graph, a frequency chart, a 3D frequency chart, RPM order, road speed view or a time domain view.
Essentials Kit and Help
The NVH system requires a PicoScope but if you don’t already have one, our Essentials Kits include a 4-channel 4425A PicoScope. The software is easy to understand and setup. Comprehensive help is available to explain likely causes and solutions, and the functions provided by the software make it easy to diagnose the problems in a logical way to reveal the root cause.
Free Software Download – Try it out!
Click to download the free automotive software: PicoScope 6 Automotive 6.12.7 (or from Pico’s download page). Once you have installed it, two programmes are available. You obviously need the scope and NVH kit to run the software properly but you can:
- Use a ‘demo device’ to see how the scope software works; or
- Load the Pico Diagnostics Package:
- Select NVH (on the left) first and then
- using the Help menu, choose Show Vibrate Help to see
- Principles of NVH Diagnosis; and
- details of many of the different vibrations you can diagnose.
