Dynamics of a three-dimensional overhead crane system

An overhead crane, modelled as a point mass carriage traversing a simply su pported Euler-Bernoulli beam that is allowed to travel in a direction perpe ndicular to its span, is considered. The point mass payload is attached to the carriage via a massless beam and is allowed both in-plane and out-of-pl ane motion. The Rayleigh-Ritz solution technique is used to obtain the equa tions of motion of the system. The influence of traverse and travel motions , pendulum length and payload mass on the pendulum motion are investigated. (C) 2001 Academic Press.
