Abstract
Numerous experiments have shown that the wheelset-track noise can be transferred by the vibration through the primary suspensions to the bogie, which is called “structural-borne sound”. The high frequency vibration transfer characteristics of primary suspensions, such as helical springs, arm bush and damper, is important. In this paper, a vehicle-track coupling dynamic model was developed considering high frequency vibration transferred by the primary suspensions. Based on the 3D finite element method, the modes of the bogie were simulated and a model of flexible bogie was established using mode superposition method. The 3D FE method was also used to develop the helical springs’ simulation model. Based on the tests’ result, the model of arm bush was established using transfer matrix method. Laboratory and field tests were carried out to validate the developed model. Short wavelength irregularities were adopted to excite the system to analyse the different influence on the structural-borne sound transfer characteristics. The results show that the vibration transmission rate is larger in 600–1000 Hz, which agrees with the test results. The model lays a foundation for analysing the sound transmission of structures.
