Energy data acquisition system X-ion™NVH

modularhigh-speed

AVL’s new, high-end module for the analysis of NVH (Noise Vibration Harshness) acquires and processes signals from microphones and vibration sensors in NVH applications. Supplemented by the new NVH acquisition module, the “multi-physics” measurement system AVL X-ion™ is 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. The increasing complexity of vehicle architectures demands extensive calibration and optimization programs. This especially includes the measurement and analysis of various kinds of acoustic signals such as noise and vibration (NVH). Over the course of product development in the automotive industry, sooner or later it is necessary to cross-correlate acoustic signals with those from the combustion engine, e-motor, inverter, and other sources. One typical requirement is the clear identification of the root cause of noise and the correlation of unwanted vibrations or airborne noises to acoustic surfaces and to electrical excitation inside the stator of an electric motor. 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. Each channel can be individually configured. All raw signals are stored in a compressed file at high resolution and in time-synchronized formats. The signals and relevant KPI’s are available in real-time and can be transmitted to an automation system or optimization software for further processing.
