В кр01Н1шейнах между пьезопреобразовател мн 3 и 4, собрашшми в пакеты, болтами 5 зажат стол 6 платформы. Пьезопреобразователь 3 и 4 изолированы от стола 6 и кронштейнов 2 изол торами 7, а с помощью вьтодов 8 и проводов 9 соединены с входными гнездами 0.

To the base of platform 1 rigidly attached brackets 2. In kr01N1 shinah between piezoelectric transformer mn 3 and 4, assembled into packages, bolts 5 clamped table 6 platforms . Piezo transducer 3 and 4 are insulated from table 6 and brackets 2 by insulators 7, and by means of leads 8 and wires 9 they are connected to input sockets 0. Known + and - denotes the polarity of piezoelectric gels. The device works as follows. When the input jacks of the electric signal are applied, the video transducers under and above the table are deformed in accordance with its shape and well, {o in the opposite directions i. if the piezoelectric transducers 3 under the table 6 of the plate of the form expand, then the piezo transducer above the table is compressed, and vice versa. In this case, the platform cion oscillates according to the nature of the input signal. Eliminating the inertia effect of the platform platform, the quality of modeling pulses with steep fronts is carried out due to the presence of additional upper transducers 4. Thus, with abrupt expansion of the transducers 3, table 6 moves upward to the strain strain of the table 6 of the platform due to inertia, it is not present due to the counteraction of additional piezoelectric transducers 4. Three abrupt compression of piezo transducers 3 additional positive piezo transducers 4) are extended and, overcoming the inertia of the platform 6. the platform, force it to move in the same manner as deformation hardening of piezoelectric transducers 3 and 4. The invention The device for investigating seismic survey equipment, made in the form of a platform with piezoelectric transducers as exciters of mechanical vibrations, installed along ;; A platform table, characterized in that, in order to increase accuracy and expand the range of research, it is equipped with additional piezoelectric transducers placed on the platform table, and the transducers are connected with respect to each other (lower to lower in polarity). attention during examination: 1.
