The quietest vehicles on the road – Test track for vehicle noise levels equipped with Siemens technology

The conditions at Natrax are ideal for this and meet both extensive national and international standards. The facility is fitted out with state-of-the-art Edge equipment including light barriers, a weather station, microphones, and solutions from the Siemens Digital Industries Software portfolio: Simcenter Scadas hardware for data capture and Simcenter Testlab Software for analysis. “Simcenter Testlab gives us a very detailed, user-friendly reporting structure,” says Sagar Bendre, project engineer, NATRAX. “It builds the standard procedures which guides us through the testing processes but also offers additional information on the vehicle’s aggregate noise performance beyond a simple ‘pass’ or ‘fail.’” The Siemens solutions allow the Natrax engineers to monitor all the test parameters in accordance with the specifications, and to compile and evaluate the data. In addition to this, Simcenter will allow multiple tests to be carried out simultaneously in the future which significantly increases the efficiency of the test track.

“NATRAX’s ambition goes beyond offering state-of-the-art, reliable service and facilities for vehicle and part homologation,” says Dr. Karuppaiah. “The analysis capabilities of Simcenter Testlab software brings deeper engineering insights into the NVH (noise, vibration, and harshness) behavior of vehicles. With our facility, equipment and expertise, we are confident that we offer the industry the toolset it needs to make the world a quieter place.”
