Kind Code:
B2
Abstract:
The testing device is essentially comprised of a testing frame (3, 4) with a base plate (1) and a fixed abutment (5). The element to be tested (6) bears by one end on the abutment (5) and is fixed by the opposite end to a load head (7) on a bearing surface (7c). A drive device (8, 13, 14) enables to move the load head (7) as a function of a member of freedom degrees which may be freely determined so that all marginal conditions of the element (6) may be set. From the ratio between the spatial displacement of the load head (7) and the forces required to this effect and provided by the drive device (8, 13, 14), of which the value and direction are measured, it is possible to determine the force and travel magnitudes in the bearing surface (7c) of the element (6). This calculation and the adjustment of the drive device for the load head (7) are carried out by means of an industrial computer, the bearing behaviour of the element (6) being detected by a progressive modification of the force and travel magnitudes.
