| description | Research on the dynamic characteristics of the vehicle-end inner windshield in high-speed EMUs is an important part of improving the dynamic performance of the vehicle-end connection system. The vehicle-end inner windshield system of high-speed EMUs was briefly introduced, and the natural vibration characteristics of the vehicle-end inner windshield was obtained through modal test. Based on the 350 km/h high-speed EMUs, the vibration test of the inner windshield and the mounting frame was carried out, and the dynamic relationship between the inner windshield and the vehicle end connection system was compared and analyzed whether or not the outer windshield had clearance. The research showed that the first eight natural vibration frequencies of the the vehicle-end inner windshield were close to each other, which made the main frequency range of the inner windshield vibration increase, and was susceptible to elastic resonance caused by broadband vibration during train operation. When there was no gap between the outer windshield, the multi-order natural frequency of the inner windshield was excited under the broadband vibration excitation of the windshield frame. When there was a gap between the outer windshield, the frequency of the pressure changed in the cavity caused the inner windshield to generate forced vibration. The study could provide reference for the design of the inner windshield fatigue life and the dynamic performance of the inner windshield structure. |
