  • DepositOnce: Numerical study of the hydraulic excavator

    Numerical experiments are carried out to study the excavator dynamic stability under different operating conditions during the motion along a vertical straight-line trajectory. It is shown that the arising inertial loads during the movement of the links along the vertical trajectory, combined with the payload swinging and the motion of the base body, decreases the excavator stability.

    Numerical analyses were carried out to investigate the contribution of the SC on the stability of Samanea saman, a common urban tree in Singapore with a shallow root system. A simplified tree-root-soil model was adopted for a parametric study by varying root length at both sides of the tree from 1 to 3 m with an interval of 0.5 m.
