Yrsle etogs) memory block 2 begins to memorize an increasing input voltage 1Gx. which is compared by a null organ 9 with an output voltage of the converter. Code-voltage 7 If the voltage value at the output of memory block 2 is greater than the values of the output voltage of the code-voltage converters 7, then the zero-authority 9 issues a second resolution. the input of the kppochevogo element 10 I: Impuetizes from the output of the pulse generator 11 are passed through the first input of the key.

element 10 to the input of the counter b impulses, increasing the number written in it. This leads to an increase in the output voltage of converter converter 7, and the balancing process continues until equality of values occurs; the voltages from the output of memory block 2 and the output voltage of code-converter converter 7.

When the input voltage reaches the maximum value, the leading edge of the positive pulse from the output of the sign determining block of derivative 1 overwrites the measured maximum code value from the pulse counter 6 to the decoder 4. The trailing edge of the positive pulse sets the pulse counter b to zero and sets switching unit 3 to position 14. At the same time, the decreasing input voltage Ux will flow to the second: input, comparison unit 12, to the first .ajto4: jt pp it goes

The input voltage from minimum to maximum decoders 5 determine the cumulative cell in the counting matrix 8, where, in accordance with the measured values of maximum and differential, one is recorded. In the counting matrix 8, each possible combination of the values of the maxima and differences in the amplitudes of the mechanical loads corresponds to its accumulative cell. Thus, during operation of the device, in each cumulative cell of the counting matrix 8, the number of repetitions of early combinations of maxima and differential values are formed, which are the ordinates of the two-dimensional discrete 3aikoHa distribution and represent the result of the modeling of mechanical loads using the maxima and differences method. From the obtained two-dimensional discrete law, the distribution of maxima and amplitudes of mechanical loads: you can get information about the strength characteristics of materials of structures under mechanical loads i
