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. |
