Train Induced Vibration

Strong motion stations have been constructed as a part of earthquake early warning system for high-speed train in China. They are deployed near railways and influenced by train-induced vibration. Then, picking seismic phase, estimating azimuth and extracting predominant frequency become difficult in this scenario. These procedures play a crucial role in locating earthquake, estimating its magnitude and then providing reliable warning to trains. In this paper, instantaneous mixing model was used to describe this problem and show that this influence could be removed by independent component analysis utilizing double sensors.

In this research, the tribological and dynamical characteristics of a brake pad with multiple blocks are investigated using experimental and numerical methods. A dynamometer with a multiblock brake pad configuration on a brake disc is developed and a series of drag-type tests are conducted to study the brake squeal and wear behavior of a high-speed train brake system. Finite element analysis is performed to derive physical explanations for the observed experimental phenomena. The experimental and numerical results show that the rotational speed and braking force have important influences on the brake squeal; the trends of the multiblock and single-block systems are different. In the multiblock brake pad, the different blocks exhibit significantly different magnitudes of contact stresses and vibration accelerations. The blocks located in the inner and outer rings have higher vibration acceleration amplitudes and stronger vibration energies than the blocks located in the middle ring.
