Analysis of the Measured Force Values in the Grab Dredger Cables
Original language description
A dredger analysis is presented in this paper. A strain-gauge device for measuring of dynamic forces in cables was designed. Measurements of typical operational work cycles during sand extraction from the bottom of water streams were done. Course of loading was elaborated into a form of two-parametric and one-parametric loading spectra of grab dredger loading. An influence of operational parameters (as extraction conditions and dredged material types) on loading was examined. Experimental measurements during operation provided basic data for an assessment of design loading spectra for dredging crane calculations according to CSN and EN standards. By means of FEM static and dynamic models, forces and local ranges of stress for fatigue damage accumulation were stipulated, especially in the welded part of dredger structure.
