| 摘要 | A resonant vibratory system utilizes nonlinear elastic transmission means to operatively connect an oscillator to a work member to provide a nonsinusoidal vibratory system having a highvelocity work stroke and a low-velocity return stroke for greatly reducing draft or propulsive load on a work member. The oscillator is coupled to the transmission means so as to be isolated from high-velocity impulses delivered to the work member. | ||||||
| 权利要求 | 1. A nonlinear resonant vibratory work system, said system comprising: an oscillator; an elongated work member, said work member being supported for a work stroke in a given direction transverse to the longitudinal axis thereof; an elastic energy transmission means operatively connecting said oscillator to said work member and operative to transmit oscillatory forces to said work member substantially parallel to said work stroke path; said transmission means including impacting means comprising a hammer for intermittently delivering an impact to said work member along the direction of said work stroke; and an elastic bar coupling said oscillator to said impacting means to isolate said oscillator from the shock of said impacting means, said bar carrying said hammer at one end and said oscillator at the other. 2. Claim 1 wherein said hammer comprises a mass supported substantially on the end of an elongated member; said elongated member being pivotally supported adjacent to said work member and extending substantially parallel thereto. 3. Claim 2 including spring means for coupling said hammer to said work member. 4. Claim 1 wherein said transmission means includes a tuning fork for coupling said oscillator to said hammer, one leg of said tuning fork supporting said hammer and, the other of said legs supporting said oscillator. 5. Claim 1 wherein said transmission means includes a first elongated member supporting said hammer adjacent said work; and, a second elongated member coupled to said first member and supporting said oscillator. 6. Claim 1 including coupling spring coupling said hammer to said work member. |
