Abstract:

The present work concerns the study of a new type of excavator considering the hydraulic arms and cylinders made of aluminum instead of the classic construction steel. The work after a first geometric evaluation of the machines on the market is realized on a machine, estimating the real geometry with which the arms are made. The most probable working conditions to which the excavator is subjected during the life cycle of the machine are studied and imployed into calculation software both to determine the dynamic actions generated by the movement and to estimate the values of the stresses, displacements and relative instability coefficients. This study is carried out both for the original steel solution and for the innovative aluminum solution. Finally the safety coefficients are estimated assuming that the cycles to which the excavator is subjected are equal to 2 * 10 ^ 6. From the analysis it emerges that the solution is absolutely constructively implementable and achievable allowing a total weight reduction (cylinder and arms) of about 65% thus allowing either an increase in the flow rate or even a reduction in the performance of the hydraulic system present on the machine.
