| 摘要 |
The invention relates more specifically to a universal machine (1) for rheological and mechanical tests for modular testing of cementitious materials as well as mining materials, asphalts, polymers, foodstuffs, drugs, cosmetics, etc. Said universal machine (1) includes an arrangement of a set of modules (CM) that form rheological and mechanical testing means for assessing rotational shear stresses as well as recording longitudinal stresses perpendicular to the direction of rotation of the AC servomotor (5), said modules (CM) comprising: a) structural layout (2), b) cabinet of electronic components (3) of the electronic system (St/Sw), c) dry step-down transformer (4), d) AC servomotor (5), e) quick connection system (Eg) for swapping shapes (18), f) testing containers (8) as well as devices for performing mechanical tests with materials in hardened state, g) charge-cell device for recording normal longitudinal stresses. Said machine (1) includes a connection with a data processing center (PC) and said modules (CM) are controlled by a specific electronic system (St) used to control speed, torque and direction of rotation. |
