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.
