Automotive NVH Data Logging for Todays Vehicles

Author - Laura


The Ford Model A was the original car produced by Ford, and was first sold to Ernst Pfennig, a Chicago dentist on July 23, 1903. Only 1,750 Model As were made from 1903 through 1904, until it was replaced by the Ford Model C during 1904.

The car came as a two-seater runabout or four-seater tonneau model with an option to add a top. The horizontal-mounted flat-2, situated amidships of the car, produced 8 hp (6 kW). A planetary transmission was fitted with two forward speeds and reverse, a Ford signature later seen on the Ford Model T. The car weighed 1,240 lb (562 kg) and could reach a top speed of 28 mph (45 km/h). It had a 72 inch (1.8 m) wheelbase and sold for a base price of US$750. Band brakes were used on the rear wheels.

Although Ford advertised the Model A as the "most reliable machine in the world", it suffered from many problems common to vehicles of the era, including overheating and slipping transmission bands. 


Cars today go through stringent tests in the development stage, before they even reach the market. 
United Electronic Industries (UEI)’s popular UEILogger Cube in conjunction with the DNA-AI-211 ICP/IEPE interface and the DNA-AI-208 or AI-224 strain gage interfaces have been used by a wide variety of customers in the study of vehicle NVH (Noise, Vibration and Harshness) characteristics.

The Cube is an ideal measurement platform for in-vehicle automobile NVH testing, being compact, rugged and running off any power supply between 9 and 36 VDC. This combination makes it easy to fit the cube in the boot, engine bay or underneath a seat. As well as logging the NVH data, the UEILogger can also acquire CAN data, allowing simply correlation between the vehicle dynamics (e.g., speed, RPM) and NVH.

All this is possible without writing any code as the UEILogger is programmed by a simple, intuitive Windows GUI.

Extra Diagnostic Power When You Need It - The GUARDIAN Series I/O boards from United Electronic Industries

Author: Laura Biddiscombe

The Guardian series of boards from United Electronic Industries (UEI) provide a host of powerful diagnostics and have been extremely popular in simulator applications as well as other applications requiring high system up-time and maintainability.

The Guardian series boards provide an extra level of diagnostics and are designed to help you quickly and easily diagnose and correct short circuits, open circuits, over-voltage conditions and many other possible failure conditions. These features are also very useful when used in conjunction with Power On Self Test (POST). All Guardian series I/O boards are shown on a green background in the latest edition of the UEI Product Catalogue - click here to request a free copy.

With so many I/O options available to the UEI's unique PowerDNA/DNR I/O interface chassis, there are virtually limitless possibilities for deployment to suit your unique application, all with outstanding software support for a great number of operating platforms including Linux, Windows and Real-time operating systems. Application packages including LabVIEW, MATLAB, DASYLab are also supported. As with all PowerDNA/DNR products from UEI, their I/O boards are guaranteed to remain available for the next 10 years.

The DNx-DIO-449 from United Electronic Industries is a 48 channel, high performance AC and DC digital input board designed for use in a wide variety of digital monitoring applications.

Sarsen Spotlight Shines on the UEI Guardian Series

United Electronic Industries (UEI) is a leader in the PC/Ethernet data acquisition and control, Data Logger/Recorder and Programmable Automation Controller (PAC) and Modbus TCP markets.

They currently offer over 50 different I/O boards for their Cube and RACKtangle chassis. The RACK/Cube versions of the boards are electrically identical and use the same printed circuit board, components and software.

The 'Guardian' series boards provide a host of powerful diagnostics, and have been extremely popular in simulator applications as well as other projects requiring high system up time and maintainability.

The Guardian series boards are designed to help you quickly and easily diagnose and correct short circuits, open circuits, over-voltage conditions and many other possible failure conditions. These features are also very useful when used in conjunction with Power On Self Test (POST).

Some of the benefits of the Guardian Series

• Built-in monitoring of output voltage and current detects shorts/opens
• PWM output and soft-start mode
• Built-in A/D converter allows actual input voltage to be measured
• Output current readback
• Output voltage readback

The PowerDNA Cube and RACKtangle I/O chassis and I/O layers are supported by all popular Windows, Linux and Real-time operating systems. The UEIDAQ Framework provides a simple and universal API and supports all common programming languages. The Cube is also fully supported by an extensive array of application packages including LabVIEW, MATLAB, DASYLab and more.

With so many I/O options available there are virtually limitless possibilities for deployment to suit your unique application. UEI also guarantees that the hardware you purchase today will be still be available 10 years from now, giving you complete peace of mind that your solution will be supported for the duration of it's life, and possibly beyond!
