英文摘要Vertical track geometry is a key parameter for monitoring the operational status of high-speed rail tracks. By integrating the axle acceleration signal, track geometry can (TGC) be obtained using an axle box accelerometer installed on in-service vehicles, offering a more convenient alternative to traditional monitoring systems such as TGCs. However, high-frequency vibrations from the axle box significantly shorten the accelerometer's lifespan, restricting the practical application of this method. To address this issue, this study proposes an isolation structure with inclined beams designed to filter out high-frequency vibrations transmitted to the accelerometer. The proposed design combines resilient cushioning and friction dissipation to attenuate high-frequency vibrations. A mechanical model of the isolation structure is developed to inform the design of the vibration isolation system for practical use. Experimental results and finite element simulations validate the accuracy of the mechanical model. Additionally, a custom acquisition device was fabricated to capture low-frequency axle box acceleration (ABA), and on-rail tests were conducted on a loop rail line. The results demonstrate that the vibration isolation structure effectively mitigates the effects of high-frequency vibrations on accelerometers while enabling accurate track geometry estimation from the acceleration signal.
