Influence of Uneven Braking of Running Wheels on Stress-Strain State of Crane Metal Structure

摘要

The analysis of the influence of the crane braking process on the stress-strain state of the elements of the metal structure is carried out. A mathematical model of the formation of external loads with uneven braking forces on running wheels, and the results of calculating the stress-strain state of the elements of the metal structure of the gantry crane in the Mathcad environment are given. Based on the results of a mathematical analysis of the obtained results, the permissible magnitude of the unevenness of the braking forces is determined. The dependences of the stresses in the most loaded node of the metal structure are obtained depending on the unevenness of the braking forces and the length of the crane span.
