Product Quality Testing (PLATO)

Campbell 2
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.
1 3 1 Testing 02
Result correlation (in-­vehicle-­to-­EOL) promotes meaningful factory based testing

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

Easy integration with machines from suppliers worldwide

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.

Plato Project Example
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
1 3 1 Real Time
Intuitive 'see-what-you-hear' real-time analyses

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.

Nvh Hardware
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)
1 3 1 Core Plato Features

Core PLATO features:

  • Multi-channel hardware/software system solution
  • Automation with test machine controllers
  • Intuitive graphical set-up
  • Precision order-locked analysis, using a product shaft speed reference signal to synchronise data acquisition to exact shaft speed
  • Automated data capture and processing environment in addition to in-depth interactive graphing/reporting
  • Expected order and unexpected ('ghost') order grading/comparison metrics
  • Pass/fail and pinpoint diagnostics
  • High-accuracy correlations (machine based testing to in-vehicle assessments)
