Zanko M. Improvement of test's methods for threshing machine of combine harvests.

The purpose of the dissertation are: to develop methods of researches, analysis, evaluation and interaction of dram thresher basis operating parameters feed rate, grain losses and damages - with a tangential threshing - separating system under test with parameters of its basis technical characteristics. On the base of scientific methods, adapted to a thresher - such a system approach, analysis and synthesis, and mathematic modeling - the normal conditions for testing were defined and methodologies of essential parameters evaluation, depending for constructional parameters and technological operational models, were developed. The developed methodologies allow to make tests - multifactor identification of a thresher independently from agriterms, with low expenses for labor and operation and high accuracy: root - mean-square error does not exceed 6,2 %.
