AVL X-ion™ NVH ANALYSIS

Your solution for acquiring and processing acoustic signals

AVL’s new, high-end module for the analysis of NVH (Noise Vibration Harshness) acquires and processes signals from acoustic microphones and vibration sensors in NVH applications.

Supplemented by the new NVH acquisition module, the “multi-physics” measurement system AVL X-ion™ is thus now the perfect solution capable of carrying out indicating, optical (VISIO) and NVH measurements alongside e-power and torque in a single system, either in-vehicle or on a test bed.

NVH Analysis

The X-FEM NVH is a 4-channel acquisition module suitable for use with all common acoustic sensor output types such as voltage, charge and ICP/IEPE. Full control over individual configurations is achieved via independent and user-definable parameters for each individual channel like resolution, bandwidth, sampling rate and amplifier gain.

All raw signals are stored in high resolution and time-synchronized in a compressed measurement file. The signals and relevant KPI’s are available in real-time and can be transmitted to an automation system (e.g. AVL PUMA) or optimization software (e.g. AVL CAMEO™) for further processing.
The optional NVH TOOLBOX for AVL IndiCom™ or AVL Concerto™ includes the most common NVH analysis tools and online NVH macros, which significantly accelerates and simplifies both data acquisition and subsequent data evaluation.

Your Solution for “Multi Physics” Measurement Tasks

Combined measurement tasks can be carried out quickly and efficiently with the new NVH acquisition module inside the AVL X-ion™ "Multi Physics" measurement system. The AVL X-ion™ includes the AVL IndiCom™ software platform thus enabling the analysis & optimization of acoustical influences and other phenomena during early stages of e-drive and powertrain development.
