响应器

When realizing on hardware, for an M×N UFPA, at any sampling time, a shift-register is used to store M data which is before the current sample data and the shift-register′s output is updated with the data which is at the same column while the upper row. Meanwhile, a common register is used to store the data which is at the same row while the previous column.

在硬件实现阶段，对于M×N的UFPA器件，在任意采样时刻，利用移位寄存器保存当前采样点之前的M个响应值，使其输出可实时更新为与采样点同列的上一个数据；同时，利用一般的寄存器实时保存与采样点同行的前一个数据，采用同帧行列间内插法实现无效像元的实时补偿。

According to structural characteristics of floating slab tracks, a track segment element was taken between two adjacent fasteners. For each element, rails were regarded as Euler beams supported by discrete viscoelastic supports. The fasteners and rubber supports were replaced by a linear spring and damp. So the vibration model of the floating slab track was established. In constructing vibration model of a metro train, each car of the metro train with two suspensions was modeled as a multi-rigid body system, in which rigid bodies were connected with each other by a linear spring and damp. Combining the potential energy of vertical vibration of the track with that of the metro train, the total potential energy of vertical vibration of the train and track was obtained. And then, the matrix equation of vertical vibration of the system was established using the principle of total potential energy with stationary value in elastic system dynamics and the "set-in-right-position" rule for formulating system matrices. The vibration responses of the system can be obtained by solving the matrix equation with the direct time integration such as Wilson-θ method.
