Accuracy of converting videoendoscopy combine harvester using generalized mathematical model

(ВЦ НУБіП України, 2018) Grubrin, O.M.; Rogovskii, I.L.

The article considers analytical models of the formation procedures for the use of video endoscopy in the assessment of indicators of a technical condition of units and mechanisms of combine harvesters. Developed electronic module for video endoscopy in the 2-s readout of the transducer. As a converter to test the correction unit was used that was developed 13-bit fiber-optic converter of the angle. Experimental studies on the installation and podtverdili that before correction instrumental error exceeding 1/4 of a quantum of high order, equal 0,703125°, and accounted for 1,266° of 1.31°. In the result of the algorithm execution code correction was able to reduce the instrumental error to 0,0089 (1.3% from 1/4 of a quantum of high order), which led to regular operation of the scheme of video endoscopy approval of samples and the formation of true sequence. The results of the processing array of the errors obtained before and after correction

Basic methodological requirements to test set of machines for poultry

(ВЦ НУБіП України, 2018) Rebenko, V.I.; Rogovskii, I.L.

The article summarizes the existing domestic, European and North American methodological requirements to test set of machines for poultry. Characterized that the method of comparing the values of indicators in the subject of complex regulatory requirements and with relevant indicators for complex analog. It is also established that the results of mathematical processing of measurement data used for comparison with the required values of technical specifications with the state acceptance tests (technical terms, if state periodic testing) for a decision on the conformity of the test complex technical requirements to technical specifications). There are two possible cases. Also, for comparison of parameters obtained in the prototype testing of complex equipment and complex analog calculate the significance of differences in means. Recommendations from the results of testing complex take on the basis of results of comparison of values of indicators of the test of complex equipment technical requirements for supply, zootechnical requirements and values for complex analog.
