Abstract
1433520 Material testing device CARL SCHENCK AG 3 Aug 1973 [4 Aug 1972 10 Feb 1973] 37006/73 Heading G1S A specimen is tested at its resonance frequency by a device which incorporates a hydraulic intensification system thereby allowing the use of relatively small masses to effect a relatively large load to be applied to the specimen. The device comprises a master piston and cylinder for coupling to the specimen, means for inducing a reciprocating motion to the piston within the cylinder, hydraulic coupling means between the master cylinder and an intensifier cylinder, and a piston located in said intensifier cylinder and arranged for coupling a predetermined oscillatory mass to the master piston. As described the specimen 2 is attached to one end of a master piston 4 which transmits the load thereto, the intensifier system 8, 9, 10 being connected via hydraulic line 7, as shown, or openings to both sides of the piston 4. The relatively small oscillating mass 11 may be connected to piston-rod 10, as shown, the intensifier system being driven by a controlling device in connection with a hydraulic power source (not shown). An exciter piston 13 may be employed, and when a constant preload on the specimen is required, the piston of a preload cylinder may be connected to the piston of the master cylinder 5, Fig. 3, (not shown) or to that of the intensifier cylinder 8, Fig. 4, (not shown). The oscillating load experienced by the specimen may, due to the intensification system, equal the square of that of mass 11, the free inertial forces being thereby diminished. In various embodiments described Figs. 5-7, (not shown), the master, intensifier and preload cylinders are mounted coaxially, the intensifier cylinder being disposed within the master piston. In yet further embodiments a pulsating load is effected by means of a single acting intensifier piston. Such a piston may be incorporated in a coaxial arrangement of master, intensifier and exciter cylinders, the single acting intensifier being mounted within the master piston. A single acting exciter piston may be mounted on the single acting intensifier piston.
