Stress-Strain State of Compound Boom of Dragline Excavator
The paper deals with the problem of optimization of steel structures of dragline excavators with compound boom. The stages of excavator boom optimization are considered. A computer-aided design system WinMachine is used for these investigations. The intermediate results of the experiment are represented by the allocation map of equivalent stress distribution and their dependence on the installation angle of installation of the bottom boom section. Recommendations are given for the angle of installation of the bottom boom section to reduce maximum stresses.
