Abstract
During normal operating conditions, electric overhead travelling (E.O.T.) cranes are subjected to severe dynamic loading. Economical design of such cranes calls for a more realistic study of the dynamic behaviour of crane operation. This paper presents a bond graph simulation of E.O.T. crane dynamics for three critical crane operations namely, load hoisting, braking during load lowering and carriage motion over three types of rail joints. Time response of girder bending stress and rope tension have been shown.
