Document Type and Number:
Japanese Patent JPH10500768
Kind Code:
A
Abstract:
A gyratory compacting apparatus for compacting a specimen of material subjected to pressure while gyrating the material includes a frame for supporting a mold, a mold gyrating carriage, a ram, and a ram driving assembly. The mold gyrating carriage receives a cylindrical mold having a cavity for holding material and an external peripheral flange about which the mold carriage is guided and driven to rotate to gyrate the mold while the ram is drivingly inserted through the open top of the mold. The ram driving assembly is supported by a flexible portion of the frame which flexes in reaction to force transferred by the ram. Strain gauges on the flexible portion of the frame provide feedback control data on ram force to an integrated computer control system which selectively controls the ram driving assembly to control the force transferred by the ram at least partially according to data generated by the strain gauges. The energy required to rotate the mold gyrating carriage around the mold is measured.
