The advent of Electric Vehicles, featuring quieter drivetrains and stiffer geometries, has prompted an intense focus on phenomena affecting Ride Comfort, such as NVH (Noise, Vibration, Harshness) and BSR (Buzz, Squeak, Rattle). To support these efforts in South Korea, Gyeongnam Technopark (GNTP) recently worked with the MTS Korea TestStand Group to build a set of chassis NVH test systems, using modular MTS components and locally sourced, MTS-designed fixturing.
The GNTP Chassis NVH Solution comprises two 4-channel test systems: a Chassis Component Test Stand (left) and a Bushing Test Stand (right). Capable of block cyclic testing and time history playout at up to 20Hz in climate-controlled conditions, both test stands are engineered to subject test specimens to real-world vibration conditions for detection and evaluation of BSR and NVH phenomena.
