This PULSE software performs modal analysis by post-processing measurement data (made with BK Connect) on the output of the structure. Because there is no need to measure the input forces, it is ideal for testing under actual operating conditions, and in situations where it is difficult or impossible to control
This BK Connect application adds to BK Connect Modal Analysis Type 8420. It enhances your structural dynamics capabilities by adding polyreference analysis of multi-shaker measurements, or impact hammer measurements using triaxial or multiple single-axis accelerometers as references. It adds best-in-class mode indicator functions (MIFs), curve-fitters and validation tools to ensure
BK Connect Modal Analysis performs classical modal analysis by extracting modal parameters from Frequency Response Functions (FRFs) acquired using impact hammer or single shaker excitation of the structure. The intuitive highly customizable graphical user-interface (GUI) is built around the analysis workflow and guides you step-by-step through the analysis with visual
BK Connect Advanced Sine Measurements is used for easy set-up, acquisition and validation of FRFs and related functions using stepped sine excitation. Stepped sine measurement is a technique, where sine excitation and corresponding measurements are made at fixed frequencies one at a time. Stepped sine measurements are often used as
This BK Connect application controls modal measurements using hammer or shaker excitation for easy set-up, acquisition and validation of data for subsequent modal analysis post-processing. This application emphasizes scalability and high productivity in the most time-consuming aspects of modal measurements: Setting up transducers, channel tables, excitation and analysis parameters Post-processing,
Geometries are essential components in structural analysis. BK Connect Geometry supports traditional test geometry functionality, but also many advanced techniques from CAE. This software is designed to handle Finite Element (FE) models with several hundreds of thousands of nodes, and of course, it easily handles typical test size geometries of
This PULSE LabShop software controls operating deflection shapes (ODS) measurements. It helps you set up, acquire and then analyse the recorded time data. From vibration signals acquired with accelerometers, it determines the vibration pattern of a structure under given operating conditions: how the structure’s dynamic properties respond to the forcing
This BK Connect software performs analysis for time, spectral and run-up/down ODS. It determines the vibration pattern of a structure under given operating conditions; how the structure’s dynamic properties respond to the forcing functions acting on it. The vibration pattern can be shown as an animated geometry model of the
This PULSE source path contribution (SPC) analysis software enables you to understand how sound and vibration are conducted from multiple sources and along multiple paths, to a person. Microphones and accelerometers measure the sources and the tactile and acoustic responses of the structure under specific operating conditions. From this, the
This PULSE software converts data and files from common CAE design programs for use in our vehicle NVH simulators and Insight simulation products. Once the CAE design data is incorporated into these simulation products, engineers, CAE analysts and non-experts can listen to and feel the NVH consequences of CAE design
Brüel & Kjær noise, vibration and harshness (NVH) simulation software is now available to automotive designers as a module, Insight+ in Altair HyperWorks CAE design software. Traditionally, CAE NVH data and results have been presented as plots, graphs and numbers. But noise and vibration must be experienced to fully comprehend
This PULSE software provides an intuitive interface for engineering work with recorded noise, vibration and harshness (NVH) contribution data. You can replay and listen to selections of the time history down to the level of individual sources and paths, and apply filters to simulate engineering changes. You can combine real-world
This software can be connected to any driving simulator to provide it with extremely realistic sound that completes the user’s perception of the virtual environment. The software synthesizes the sounds in real-time for the driver’s vehicle, the surrounding traffic and the ambience. Because this NVH simulation responds accurately to the
This PULSE software auditions the exterior sounds of real vehicles or virtual vehicle designs, as they drive through highly realistic scenarios. You can programme the vehicle to perform any driving manoeuvre such as moving away from a car park, or accelerating rapidly – in any realistic urban scenario. You can
VSound is a multi-channel portable system that can be used to provide synchronized signals for speakers or other dynamic actuators, allowing individual sounds for inside and outside the vehicle to be generated simultaneously for evaluation of virtual vehicle prototypes. The system delivers exceptionally high‐quality audio signals – from complete engine
This PULSE software creates an interactive driving experience of a vehicle’s interior noise, vibration and harshness (NVH), enabling the actual experience of sound and vibration data. Highly accurate vehicle sound is played through headphones or speakers, allowing the driver to experience the sound quality of a vehicle throughout all of
This PULSE software interface enables you to set up and test audio devices on a PC via a high-quality sound card. It does this by working together with our USB Audio Interface hardware. You simply plug the device under test (DUT) into the hardware box, which connects to your PC
