    Rail transit, Vehicle NVH

    The Rail Transit Acoustics Laboratory is mainly used for the research of materials, components and vehicle-level acoustic characteristics of metro, train, etc. It provides experimental support for theoretical research, product development, and performance verification. The acoustic laboratory mainly consists of vehicle hemi-anechoic room, anechoic room, standard reverberation room, sound insulation equipment, control room, and sound quality room.
    NVH behavior of the vehicle is one of the major issues that most of international automobile manufacturers and automotive parts suppliers concern.
    SWAT has accumulated a wealth of experience in the construction of various NVH test laboratories for rail transit and automobile, and has a solid theoretical foundation and practical experience. We can provide an acoustic environment that meets the relevant test standards for the noise and vibration test, evaluation, analysis, diagnosis, and improvement test of various passenger cars and commercial vehicle engines. And this kind of environment, at the same time, meets the requirements  of the vehicle, engine, and material components’ acoustic performance test.
