Elasticity modulus of construction measurement appts. for earth and construction materials - has base housing contg. lifting magnet for supporting variable number of load plates and exerting force impulse onto upper or lower plate. |
摘要 |
A plate is laid on the structure. Various load plates are placed on the first plate to produce different load pressures on the structure. A vibration stimulator and sensor with evaluation electronics determine the mean vibration period. The first plate forms a wall of a housing (12) with an external supporting surface (62) and an opposing external plate (72) on which the load plates (16,18,20) are placed. A lifting magnet (84) inside the housing has a movable element whose direction of motion can be selected. Depending on this direction the magnet exerts a force on the upper or lower plate when actuated. ADVANTAGE - Enables different application areas to be achieved with same components and vibrations to be stimulated rapidly and simply and without component stress.
