Researching of the Dynamic of Hoist Dragline Excavator ЕШ-15/90а Drive
This article surveys an analysis of dynamic processes of hoist of the excavator-dragline type ЕШ-15/90 using computer simulation, considering the effect of sagging of the rope. A comparison of the accuracy of the obtained computer models with and without the nonlinearity of its elasticity coefficient is considered. Structural models with the use the libraries of MATLAB + Simulink mathematical program are proposed to solve this problem.
