Dynamical research on groung pressure of large-scale mining crawler excavators

Due that the groung pressure is a key criterion for crawler machinery performance evaluation,the walking mechanism of large-scale mining crawler excavators is studied.Under two typical working conditions,i.e.the limited slope and steering,the dynamical simulation is conducted using such dynamical analysis software as ADAMSTM.By the means of qualitative and quantitative analyses,the groung pressure distribution of walking mechanisms is investigated on large-scale machinery without physical experiments.In so doing,this approach sets a basis on loading distribution depth and performance analyses.
