摘　　要：建立了前顶直推式与后置前推连杆组合式两种举升机构的动力学模型,根据其动力学模型使用仿真软件对前轴压力在举升过程中的动态变化规律进行仿真。根据仿真结果及侧翻稳定性判定公式分析得出,在相同的条件下,举升倾卸时前顶直推式举升机构比后置前推连杆组合式举升机构具有更高的抗侧翻能力。The dynamic models of former straight-push lifting mechanism and rear front-push and connecting-rod lifting mechanism was established. Based on the dynamic models, the dynamic change rules of front-axle load with simulation software during the course of lifting was simulated. According to the simulation results and estimate formula of rollover stability, under the same condition, the former straight-push lifting mechanism has stronger anti rollover stability than rear front-push and connecting-rod lifting mechanism during the course of lifting.
