2024年10月4日 · Noise, vibration, and harshness (NVH) are critical aspects of vehicle quality that automakers strive to master. In the automotive industry, the pursuit of reducing NVH levels is relentless, as they directly impact the comfort and perception of quality for …

2024年10月8日 · Noise, vibration, and harshness (NVH) analysis in automotive engineering is a critical aspect of vehicle design and performance. NVH refers to the study of unwanted noise and vibrations that occur in vehicles and the efforts to minimize them to improve overall ride quality.

This playlist contains basic tutorials which introduce the practical applications of NVH and vibration analysis of mechanical structures using FEM.

2019年2月7日 · NVH analysis is a crucial aspect of vehicle design and manufacturing. It involves evaluating and minimizing the levels of noise, vibration, and harshness that a vehicle produces. This analysis aims to create a comfortable and enjoyable driving experience while also ensuring the vehicle’s reliability and safety.

Hexagon offers an end-to-end solution for NVH with industry-standard tools that allow engineers to optimise the structural behaviour (vibrations), encapsulate noise sources (acoustic materials) and reduce the emission levels of the powertrain (gears and bearings).

In order to deal with this frequency range effectively, our PicoDiagnostics NVH kits contain both microphones (for sound), and accelerometers (for vibrations). Traditionally, NVH problems have been viewed as difficult to solve, with NVH complaints being subjective as people have different levels of NVH acceptance or feeling.

2023年4月13日 · Noise, vibration, and harshness (NVH) is the study and measurement of aural and tactile feedback in an object. Because sounds can be both an annoyance and a benefit, NVH analysis helps identify where a sound is coming from and why.
