摘要
针对刚度和阻尼可以调整的磁流变隔振器在地铁轨道的垂向隔振性能进行了研究。分析了如何调整磁流变隔振器的刚度和阻尼实现优化地铁浮置板轨道减震、隔振效果。在ANSYS里建立地铁列车水平运动的垂向振动等效模型进行力学分析。通过调节刚度和阻尼观察地铁轨道等效模型的减震、隔振效果的变化,得到提高轨道的减震、隔振性能刚度和阻尼的优化范围,从而实现比传统被动隔振器更理想的振动特性。
Study on the vertical vibration isolation performance of the Metro Rail according to the stiffness and damping can be adjusted to the magnetorheological vibration isolator. The analysis of how to adjust the stiffness and damping can optimize the damping and vibration isolation effect of the floating slab track of the Metro Rail. We establish the equivalent model about vertical vibration of the horizontal movement of the subway train in order to make mechanical analysis in ANSYS . By adjusting the stiffness and damping, we can observe the changes about the damping and vibration isolation effect of the floating slab track of the Metro Rail, and have improved the performance of the damping and vibration isolation as well as optimized the scope of the stiffness and damping. Thus, we can realize the vibration characteristics which is more desirable than traditional passive vibration isolator.
