Abstract:
To investigate the vibration characteristics of medium and low speed maglev vehicle-bridge coupled system, field dynamics tests were carried out at Shanghai Lingang Medium and Low Speed Maglev Test Base, the effects of vehicle speed and structural form of the bridge on the dynamic response of the coupled system were studied. The levitation frames with mid-set suspension was adopt by the test vehicle, while the test bridges were 25 m simply-supported with concrete and steel structures. Modal tests were performed to clarify the natural vibration characteristics of the two bridges. The acceleration of the vehicle-bridge coupled system and the vertical dynamic displacement signals of the bridge under different operating conditions were extracted. The key dynamic indicators of the vehicle-bridge coupled system such as the vertical and lateral Sperling indexes, dynamic coefficients, and rotation angle of the beam end were calculated, the dynamic response characteristics of the coupled system were analyzed in detail, and the vibration level of the system was evaluated. Research results show that the vertical first-order natural frequencies of the concrete bridge and steel bridge are 7.32 and 7.72 Hz, respectively, and the key dynamic indicators of these two bridges meet the requirements of relevant standards. The maximum acceleration of the concrete bridge and steel bridge are less than 0.2 and 1.4 m·s-2, respectively. When the vehicle is operating at 5 km·h-1, the amplitude of vertical dynamic response of the steel bridge is approximately 7.6 times that of the concrete bridge. In the speed range tested, the lateral Sperling index of vehicle is less than 2.5, indicating excellent lateral operation stability when the vehicle is running on the concrete bridge and steel bridge. The peak of the vertical natural frequency of the vehicle's air-spring suspension system reaches its maximum when the vehicle speed is 25 km·h-1, and the vertical Sperling indexes reach 2.687 and 3.340 when the vehicle passes through the concrete bridge and steel bridge, respectively. The test results can provide valuable references for the optimal design and numerical model validation of medium and low speed maglev vehicle-bridge coupled system. 1 tab, 19 figs, 26 refs.
