In this way, the traveling frame will obtain a lateral initial velocity. Because the lateral sliding resistance of the vibrator roller 34 is very small, the traveling frame will smoothly transition to another lane. It can be seen in the figure (b) that the oscillators in the two channels are staggered, which makes the waveform bar have no falling points in the horizontal direction, so the waveform bar will not leave the oscillator roller 34 during the channel changing process.

Twice, the vibrator in the straight path is three-phase, and the switching path is equivalent to six-phase.
  • the reason why the vibrators arranged in the groove can form a unique train of motion waves is not only related to the arrangement of the vibrators, but the most important thing is that the vibration of each phase vibrator originates from the same circumferential movement. As shown in the figure below, it is very clear. The more the number of oscillator phases, the more complete and smooth the waveform of the moving wave.
  • Increasing the number of vibrator phases in the switching path to six phases does not require six total drive cables. This is because in a six-phase vibration, the phase difference between each two adjacent phases is 60 degrees, so there are always two phases with completely opposite vibration states. , Such as A and E, B and F, ⁇ and 0 in the bottom left figure. In this way, a two-phase vibration can be driven by a transmission cable. As shown in the lower right figure, when the transmission cable moves up, it drives E, and when it moves down, it pulls A again. Therefore, the six-phase vibration in the switching lane can still be hauled by the three main drive cables.
