Key Features
Add-on
High-fidelity results for accurate pass/fail and pinpoint diagnostics
Leading-edge NVH product testing technology with a worldwide reputation for delivering meaningful results day-in, day-out
AB Dynamics has over 30-years of experience designing, deploying and supporting production testing systems where noise/vibration measurements (or signatures) are used as primary indicators of product quality.

Our supply model is based on :

· Advice - on test machine design, sensor choice and location, data capture and analysis options
· Product - feature-rich and robust application software
· Services - software set-up, test proving, training
· Support - ongoing assistance for new test set-up, result interpretation, fault-finding etc
Testing environments
We are best known for providing highly responsive end-of-line (EOL) test systems, but our systems also meet requirements in the following areas :

· In-process test
· Audit test
· In-vehicle test
· Exterior (pass-by) noise diagnostics
· Durability (endurance) monitoring
· R&D/Product development
Result correlation (in-vehicle-to-EOL) promotes meaningful factory based testing
Add objectivity to your powertrain, power-steering and auxiliary products
Products tested
· Axles (front/rear, independently-suspended, beam, with/without tubes, with/without drive-shafts)
· Transmissions (manual, automatic, automated manual, dual-clutch, CVT)
· Transfer cases (4x4, SUV, commercial vehicle)
· PTUs (power take-off units)
· Differential units (4x4 front-rear)
· Engines ('cold' & 'hot')
· Power-steering (hydraulic, electro-hydraulic, electric)
· Rolling-element bearings
· Motors
· Alternators
· Pumps & compressor
Global cooperation
For machine-based testing, we work with test machine providers worldwide to integrate our systems into fully-automated test facilities. Please contact us if you're searching for a test machine supplier.
Easy integration with machines from suppliers worldwide
Highly interactive environment for set-up, result viewing & processing
PLATO - Core NVH Measurement & Analysis Software
PLATO software forms the highly-configurable core platform for all our NVH test solutions. It :

· Structures your resources
· Defines test profiles/sequences
· Configures data capture and analysis
· Orchestrates results storage
Real-time analysis in production test mode
Swap PLATO into production test mode and it waits to receive information on the product to be tested before automatically sequencing through a test schedule defined specifically for the product model being tested. Integrated data capture and real-time parallel processing ensures that results are available as the test progresses. OPC (software) handshaking with test machine controllers (PLCs, PCs etc.) is a standard feature.
Intuitive `see-what-you-hear` real-time analyses
Support for a wide range of dynamic sensors and National Instruments data acquisition hardware
Hardware
We can recommend and supply the measurement and analysis hardware, but many customers, including machine builders, opt to source this hardware themselves to reduce costs.

· Sensors, cables, powering/conditioning
· Data acquisition ('DAQ') hardware (all our systems use National Instruments™ (NI) DAQ-hardware, readily available worldwide. Click here to view a list of supported NI DAQ-hardware)
· Computers (for test stations and servers for data storage)
Key Features
Multi-channel hardware/software system solution
Automation with test machine controllers
Intuitive graphical set-up
