基于ADAMS的矿用汽车液压举升系统建模与仿真

his paper makes a study of mining trucks’ lifting system in ADAMS software. By entity modeling, the hydraulic lifting system simulating model of some mining truck is established, and simulating is done. The result of simulating indicate that in lifting process, the rate of box rotation increases gradually, multiple oil pressure impulse appears in the rodless cavity of lifting cylinder. Along with box raising and fallback, the force in lower anchor chair of lifting cylinder increase firstly and then decrease. The force in anchor chair short-time oscillates at the time of every cylinder outing. By mechanism-hydraulic coupling simulation of mining truck hydraulic lifting system, the process of interaction between mechanical system and hydraulic system is clear, which offers design basis of mining truck lifting mechanism and hydraulic system. The result of test proved the validity of simulation in this paper.
