What is NVH solution?
Table of Contents
Creating new value that contributes to realizing a safe and comfortable mobility life with control of vehicle noise and vibration. *NVH is an acronym for Noise, Vibration and Harshness. …
What are the various applications of NVH test equipment?
Many industries, ranging from automotive & transportation, aerospace & defense, power & energy, and consumer appliances, use NVH testing equipment. These equipment include sensors, transducers, data acquisition systems, signal conditioning systems, and analysis software to measure the noise and vibration levels.
What is NVH consideration?
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks.
What is passing noise?
A vehicle test that refers to a procedure of measuring the noise emission levels on an exterior test track is called pass-by noise test. The pass-by noise test is aimed to reflect the exterior noise emission levels from the vehicle in an urban traffic environment.
What are NVH papers?
The SAE International Journal of Vehicle Dynamics, Stability, and NVH is a scholarly publication of original research and review papers focusing on vehicle dynamics, stability, noise, vibration, and harshness (NVH).
How do you test for NVH?
Techniques used to help identify NVH include part substitution, modal analysis, rig squeak and rattle tests (complete vehicle or component/system tests), lead cladding, acoustic intensity, transfer path analysis, and partial coherence.
What is passing noise test?
VBOX Pass-By Noise testing equipment allows you to log channels such as engine RPM, vehicle velocity and maximum vehicle exterior noise to the accuracy requirements of ECE/ EPA standards and regulations.
Why NVH analysis is important?
Every object that moves or is put into motion can cause potentially critical noise and vibration problems. In combination with motor vehicles, NVH is an important criterion for driving comfort. This includes the sum of all audible and perceptible vibrations that affect this comfort.
How do you increase your NVH?
There are three ways of improving NVH: Interrupting the noise or vibration path, with barriers (for noise) or isolators (for vibration). Absorption of the noise or vibration energy, as for example with foam noise absorbers, or tuned vibration dampers.
Why is NVH needed?
What is pass-by noise of a vehicle?
Pass-By Noise Testing with VBOX VBOX Pass-By Noise testing equipment allows you to log channels such as engine RPM, vehicle velocity and maximum vehicle exterior noise to the accuracy requirements of ECE/ EPA standards and regulations.
How do you measure NVH?
Typical instrumentation used to measure NVH include microphones, accelerometers and force gauges, or load cells. Component and subassembly NVH tests are most commonly performed using a vibration shaker while entire vehicles usually on the test track or road simulator testbeds.
