  • Intelligent & Meaningful Noise/Vibration Testing For Powertrain Product Quality Assessment

  • Fact: Meaningful Noise/Vibration Testing at the End-of-Line (EOL)

    Can Save Your Organisation Money. End-of-Message

    A few minutes of your time watching this presentation will show you how our NVH technology can empower your manufacturing plant

  • First, let’s look at the product types tested: Transmissions manual, automatic, auto-shifted manual, CVT, passenger/truck & bus

    Transaxles manual, automatic

    Transfer Cases & Power Take-Off Units (PTUs)

    Axles Independently-Suspended, full-beam, with/without tubes/drive-shafts

    Gear-Sets Ring & pinion, spiral bevel, parallel axis

    Power-Steering Systems

    Hydraulic, electro-hydraulic, electric

    Engines “hot” and “cold”, end-of-line, audit,

    durability, R&D

    Motors, Compressors, Fans

  • OK, we can hear you saying,

    “I can buy an NVH system from one of tens of suppliers, and my machine builder can even embed

    a system for me. Why would I choose ABD?”

    Experience – we have over 50 man-years experience in designing, developing, deploying & supporting

    systems worldwide

    Here are some of the reasons...

  • And … Know-How – we are NVH- engineers who understand your

    products and the manufacturing challenges involved

  • … as well as

    Track Record – we have a history of successful installations dating back to 1986, where “successful” means:

    • creation of objective results that correlate with objective and subjective assessments in-vehicle

  • We Are Independent – we integrate our systems with any machine builder of your

    choice worldwide

    You choose the machine and we deliver a standard NVH

    result

  • And …

    We use Commodity Hardware – our systems use worldwide standard data acquisition (“DAQ”) hardware from

    4-channels

    through to …

    16-channels as standard

    • fast delivery of spares worldwide • 24-bit sampling accuracy • bandwidth to spare • source in your territory if you prefer

    … and we use standard PCs - desktop / industrial

  • … our key strengths include:

    Variable Speed/Torque Testing

    • mimic the way your customer uses your product

    combined speed and

    torque sweeps ..

    … speed sweeps, torque sweeps

    you name your test and we’ll:

    • automatically learn your requirements

    • monitor your test machine consistency, day-in, day-out

  • Highly Configurable Software

    • Windows™ Vista/XP/2000 software • Windows™ 7 ready • Intuitive tree structure set-up • Easily reconfigured when your testing requirements change

    … protect your investment:

  • “See What You Hear” Powerful Real-Time Analyses

    • utilises your PC’s multiple processing cores

    • no requirement for plug-in DSP hardware

    • Real-time order-tracks

    • Immediate visual indication of pass/fail

    • Pinpoint diagnostics for failures

    Missing Bearing

  • Now let’s watch a typical production test cycle: • Details arrive

    Waiting for details of the next product to test...

    • Real-time key order track displays (result, acceptance level)

    • Speed sweep up, then down in 5th gear

    • Followed by speed sweeps in 3rd gear

    • and then reverse gear to finish

    • a displayed order track fails

    • easily interpreted summary test report

  • Freeze-frame summaries available before next test

    Review test conditions (speeds, torques etc.) for a test stage

  • Review an analysis that was conducted in background e.g. ghost-order detection

    Or “knock” & “click” analysis locked to each shaft in motion

  • Flexibility

    Large Library of Parameter (“key feature”) Extraction Methods for Pass/Fail Formulation

    • absolute metrics:

    • peak level • average level • area under trace

    • relative metrics:

    • difference from acceptance level

    Large relative difference between result and acceptance level

    ignored by peak level !

    ignored by average level !

  • Plus, in-depth analysis/reporting:

  • All results in easy to access SQL database:

    SQL

    NVH Results

    Your software Your reports etc.

    ABD software

    Standard reports

    OR

  • Small Footprint:

    No Requirement for Standalone Equipment Rack

    • DAQ-hardware inside PC • PC can be dedicated to NVH or be shared with test stand control

  • You can run “core” PLATO for basic analyses, or you can add one of the following sub-products to tailor your application:

    We call it “PLATO”

    Revkit – knock & click analysis

    Stats – on-line SPC, trending etc.

    Focus – fault- classification/reporting

    Dybal – dynamic balancing

    Metkit – pitch-line run-out (PLRO)

    Passby – order analysis on the track

    Nuren – engine work-cycle mapping 05
