摘要:用滤波后摆式列车的未平衡加速度作为控制信号,可实时地控制车体的倾摆角,从可靠性角度出发, 进行了加速度传感器的选型和安装位置的比较,验证了陀螺仪的测试精度。得出结论:可利用陀螺仪的输出作 为触发信号以及倾摆的极性判断。Abstract:Using the filtered non-balanced centrifugal acceleration as control signal, the tilting angle can be controlled on real time. The choosingof the acceleration sensortype and the comparingof the fixing position are made from the view of reliability. The measurement precision of the gyroscope is verified, and the conclusion of getting the trigger signal and the polar judgment of the tilt according to the output of the gyroscope is proposed.
