The paper comprises the results of the analysis of the fatigue strength of the framed shaft headgear structures, among them a multiple-rope hoisting plant, resting nodes of guide pulleys. The analysis was carried out on the design model consisting of flat and spatial finite elements within the software complex “Ansys Workbrench 14.0”.
Frequency analysis and results of a research of a force sensor of a mechatronic manipulator in stressed state are presented. The finite - analytical model of a sensor for holding finite element analysis was designed.
The results of numerous researches the patterns of distribution of local stresses in the nodes supporting the guide pulleys. Research was carried out considering dynamic nature of the load. Mathematical modeling was carried in four stages, which revealed the influence of the degree of idealization and design scheme and set the boundary conditions of interaction nodes supporting the guide pulleys to the rest of the building.
