IVA Noise & Vibration Analysis


iVA - The next level in noise & vibration analysis!

Quickly pinpoint where the vibration is coming from

- Which Wheel/Suspension (LF-RF-LR-RR)
- Which Brake (LF-RF-LR-RR)
- Which Driveshaft (Front- Rear)
- Engine and Engine Driven Pulleys
- Transmission and Transfer case

The iVA uses Quad Vibration Technology™ (QVT)

This technology locates and identifies the vibration

then rates the vibration severity with advanced color

coding. The iVA locates multiple vehicle vibrations

simultaneously. The iVA displays a vehicle topology map that highlights the severity of vibrations with yellow, orange, and red. No need to analyze graphs or charts, but these are easily accessible at any time.

The iVA simplifies setup!

Eliminates the need for separate hardware such as an oscilloscope and J2534 device. All you need to start testing is your Windows PC. To start; enter the Tire Size, Ring and Pinion Ratio and Vehicle Drive Type (Front Wheel Drive, Rear Wheel Drive, All wheel drive, and Four Wheel Drive). If the Ring and Pinion is unknown the iVA will automatically calculate the Ring and Pinion Gear Ratio. Simply attach the magnetic sensors to the suspension components. Setup takes less than 5 minutes in most cases!

Comes with everything you need for use on your Windows based PC

The Intelligent Vibration Analyzer Module™ (iVA Module) houses an advanced electronic system that contains a Data Acquisition Device (DAQ) for sampling the signals from the Smart Vibration Sensors and iVA Microphones. The iVA Module also contains a Vehicle Communications Interface (VCI) that communicates with vehicle Engine Control Modules from 1996 to present. Communication Bus Types Supported; J1850 VPW, J1850 MPW, J1850 PWM with IFR, ISO 9141-2,  KPW2000, KPW2000 Slow init, and CAN.
The Smart Vibration Sensor™ (SVS) uses multiple 3-axis accelerometers (X, Y and Z) to locate vibrating components. These are smart sensors in that they allow all three channels from the accelerometer to be monitored at all times. This is accomplished by summing the X, Y and Z channels being monitored within the vibration sensor itself. That way the total amplitude produced from the X, Y or Z channels is analyzed. This will enable the DAQ to read the total amplitude from all three accelerometer axis produced from the sensor providing vibration in all directions. When four vibration sensors are used the iVA DAQ can monitor 12 accelerometer (X, Y and Z) axis continuously.
