| 摘要 |
The invention relates to a device consisting of at least one power unit (3) which is suitable for acting on a structure (7a) to be tested with an adjustable force (2a) by means of a suitable support (7), of at least one displacement transducer which detects the displacements of the structure (7a) to be tested compared with a support (7b), of control systems (B) for the loading and the transducers, of a signal recorder (A) and of amplifier-transmitter-receiver devices (c) of "signals" from the transducers. <IMAGE>
