Source Path Contribution Type 7798
|
Uses
• Understand primary sources of sound and vibration perceived at the driver or other receiver position
• Understand routes sound and vibration travel from source to receiver
• Airborne and Structure-borne sound transmission path analysis
• Perform standard source path contribution analysis (transfer functions and operating conditions) for engine, powertrain,
• Complete driveline, road noise and virtually any source-path-receiver situation
• Determine contributions ranking in the frequency, order or time domains
• Target setting with ’what-if’ scenario applications
• Virtual prototyping and hybrid modeling, combining test data with your CAE or target data
• Evaluation of design alternatives and their effect on the driver or other receiver
• Contribution analysis in conjunction with the Brüel & Kjær NVH Simulator
• Listen to and modify contributions
Features
• Time domain and frequency domain calculations for mount stiffness, impedance matrix and source-substitution methods
• Intuitive playback and analysis of Time Domain SPC results using SPC Time Insight module or NVH Desktop • Simulator
• Structure-borne contribution analysis (mount stiffness and impedance matrix)
• Airborne source substitution methods
Multiple Coherence method (used, for example, for fast road noise investigations) with no need for transfer functions
Open data structure – easily utilize data from a virtually any test, measurement and CAE product through UFF/UNV and other file formats
Management of sources, paths and receivers in a structured model
Matrix Inversion Tool with robust inversion algorithms to determine forces and source strengths when using the Impedance Matrix and Source Substitution methods
Pre-configured SPC measurement templates for easy measurement process
Export time data for post-analysis, such as order extraction with PULSE Reflex™ or PULSE LabShop
Source Path Contribution Type 7798 (SPC) enables the engineer to understand how sound and vibration are transmitted through both structure-borne and airborne paths. And with the exclusive Bruel & Kjaer SPC Time Insight time-domain analysis and playback technology, you can listen to the components of the sound and create virtual prototypes.
