Abstract


Paper presents a method of simplifications used over numerical studies on dynamic properties of a hydraulic loader crane. Simplification concerns hydraulic actuators and allows for a significant reduction in the time of building model and calculations. Modal analysis of a loader crane using the finite element method, for both complex and simplified models, was carried out. The modal analysis computation times for both models were compared. Next, the results obtained on the basis of simplified model were compared with the results of experimental studies.
