The Noise, Vibration, and Harshness Sector at SunTrax is designed for specific applications, such as sensor vibration behavior testing, sensor durability testing, and vibration control systems testing, utilizing varied pavement materials along 500 ft (152.4 m) of track.

Variations Beyond Your Requirements

The Noise, Vibration, and Harshness Sector, a collection of eight unique surfaces in one restricted area, is in the central-east portion of the complex and provides a secure location to test vehicle sensors’ exposure to noise, vibrations, and surface harshness. Supporting up to three users simultaneously, this area can be segmented into three smaller test spaces to provide maximum flexibility and efficiency.

In addition to the various surfaces is the adjacent External Noise Track, which consists of a two-lane straightaway with a loop at either end for continuous circulation. The interior of the northern loop is fully paved to test lateral force application and braking scenarios and can support up to six vehicles and ten users simultaneously, depending on the testing scenario.

External Noise Track

The External Noise Track was designed to substantially conform with the ISO 10844 standard and features a drive lane that is 131 ft (40 m) long x 24 ft (7.30 m) wide asphalt surface, plus asphalt propagation areas that are 65 ft (20 m) x 65 ft (20 m). The track is a great alternative for developmental testing where cost and schedule are important considerations, and a certified track is not required. Homologation and legal testing can subsequently be completed on an ISO 10844-certified track.
