Vibration and Noise Research Institute

Vibration and Noise Research Institute has 3 teachers, including1 associate professors, 1 Senior Engineer and1 lecturer.

Vibration and Noise Research Institute is based on the national key disciplines of vehicle application engineering, the reliability of the vehicle structure and the ministry of education of engineering center of monitoring technology. After years of development, Vibration and Noise Research Institute gradually formed rail transportation vibration noise research for scientific direction characteristic. Our research directions are the mechanism of the development of vibration noise and the control technology of the wheel-rail system, rail transport system aerodynamic noise mechanism and control technology, the in-car vibration noise control technology, Low-frequency noise control theory and technology, Vehicle operation noise identification technology, environmental monitoring and control technology research.

The Institute has a number of advanced teaching and research equipment and related software and has the capability of sound insulation test components. The main equipment and software are as follows:

1)     The BBM48 channel noise and vibration test of acoustic vibration source identification system (acoustic array, transfer path analysis and synthesis);

2)     32- channel acoustic vibration data acquisition and analysis system;

3)     Danish B & k's sound intensity analysis system, sound and vibration testing system 3534;

4)     Belgium LMS company’s software of SYSNOISE for structural acoustics simulation and analysis;

5)     The software of RAYNOISE for geometric acoustics simulation;

6)     The U.S. software of MESCOPE for experimental modal analysis;

7)     With the ability to apply the VA-ONE of finite element and statistical energy analysis for railway noise analysis;

8)     With the ability to apply the vehicle's aerodynamic noise simulation analysis;

9)     Acoustic test room for parts;

10)   The sound absorbing performance test equipment;

11)   The vibration excitation and measurement system;

At present, this institute has directly undertaken from Railway Corporation, the Ministry of Finance and other longitudinal, transverse project more than 40 projects, and achieved a number of important research results. This institute was awarded the third prize of Beijing scientific and technological progress.
