Estimation of fatigue life of a floating crane boom CPL 16-30 on the basis of the equations of damaged environment mechanics
The article considers the problem of estimating the fatigue life of a metal floating crane boom in its actual operational loading. To assess the generated life and to predict the residual life of the crane steel structures, the final element analysis of the kinetics of the stress-strain state of the dangerous zones of the floating crane boom KPL 16-30 is performed and an assessment of their fatigue life is made on the basis of the equations of damaged environment mechanics. Analysis of the results allows approaching the problem of extending the life of the cranes, which have worked out the standard period, in a reasonable way.
