IPC: G01M10/00
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To obtain a wave formation method in which regular waves and irregular waves which are advanced to the obliquely preceding direction of every wave formation plate can be generated by a wave peak line formed of the envelope of waves generated by every wave formation plate by a method wherein a plurality of wave formation plates are arranged in a row, every plate is driven individually, the periodical motion of every plate is controlled and a control device is controlled by a predetermined wave-formation instruction signal. SOLUTION: A plurality of wave formation plates P are arranged in a row. They can be arranged in an arbitrary arrangement such as in a line shape, a curve shape, an oblique straight line shape or the like in addition to a straight line shape when a coordinate position used for a computing operation is set. The plates P are periodically moved back and forth at a hinge part to every adjacent wave formation plate by driving gears D. A wave-formation instruction signal to a control device C is given to the control device C which has a predetermined cycle, a predetermined phase difference and a predetermined amplitude according to the advance direction of target regular waves in such a way that a phase difference is generated in the periodical movement of every adjacent plate P by means of a snaking principle.  Thereby, every driving gear D moves every plate P back and forth on the basis of the snaking principle, and regular waves are generated in the advance direction of target waves by a wave peak line formed of the envelope of waves generated from every plate P.
