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:

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 0
