The analysis of the intense-deformed condition of the basic bearing elements of frame mowing mine headgears
Abstract: The numerical analysis of the intense-deformed condition of the basic bearing elements of a typical frame mowing mine headgear is made. The analysis has been made of two finite element for the design models realized in program complexes SCAD and LIRA in the form of rod and lamellar approximation of elements. For rod settlement model the elastic-plastic analysis is made. As a result of calculations parameters of the intense-deformed condition, spectra of own frequencies of fluctuations, factors of a stock of system stability, as elastic system are received. As a result of comparison of the received results a number of constructive elements of the headgear for which calculation under the settlement scheme in the form of rod approximation gives a considerable error is established. Recommendations for the design of frame mowing headgears with use of the settlement models consisting of cores and plates are presented.
Keywords: mine frame mowing headgear; the settlement scheme; computer modeling; elastic plastic analysis; intense-deformed condition; operating ratios on pressure; factors of a stock of stability of a construction; a spectrum of own frequencies.
