Abstract

A modified technique for dynamics and stress analysis of articulating cranes with application to non-telescoping boom manipulators is proposed. The crane is modelled as an open-loop rigid body system. Finite element method is used for stress problem solution in replacement of the previously applied beam theory based algorithm, providing higher accuracy and ability to analyze structural members of a complex shape. The proposed technique is implemented in software KBCrane. The brief review of the suggested strategy with main emphasis on performance issues is given in this paper.
