摘要： PURPOSE:To manage rationally comfortable ride feeling of a track by outputting a waveform which has been made to pass through a comfortable ride feeling processing filter, against a displacement of the left and right of a rail to an inertia space, and putting stress on adjustment of a line deviation of a place where said waveform is large. CONSTITUTION:For instance, a right and left direction displacing signal of a left rail outputted from a right and left displacement detector 9, and a speed signal outputted from a speed signal generator 17 are inputted to a high-pass filter circuit 13, and the right and left direction displacing signal of the left rail, whose low frequency component has been cut is outputted. On the other hand, a right and left direction acceleration signal of measuring frame, outputted from an accelerometer, and the outputted from the speed signal generator 17 are inputted to an integration circuit 14 twice, and a signal which has been intergrated twice is outputted. Two signals concerned are added by an adder 15, and outputted as the right and left direction displacing signal of the left rail to an inertia space, whose low frequency component has been cut. Also said signal is inputted to a comfortable ride feeling processing circuit 16 together with the speed signal, and a comfortale ride feeling processing line distortion waveform of the left rail is obtained.
