摘要
本文在对某型登车桥液压系统工作原理进行分析基础上,利用AMESim仿真软件建立了对应的仿真模型,仿真验证了模型的正确性。同时发现登车桥液压系统主液压缸在下降过程中势能直接转化为热能消耗掉,没有很好的回收利用,造成系统升温,影响系统的使用性能及寿命。鉴于此,本文提出了一种通过蓄能器在主液压缸下降过程中将能量回收,上升过程中将能量释放来驱动伸展延伸板液压缸。仿真结果表明蓄能器能量回收系统达到了一定的能量回收效果,节能效果较为显著,能量损失也得到了降低。所得结论对登车桥液压系统优化设计有一定意义。
Based on the analysis of the working principle of the hydraulic system of a certain boarding bridge,a corresponding simulation model is established by using AMEsim simulation software,and the correctness of the model is verified by simulation.At the same time,it was found that the potential energy of the main hydraulic cylinder of the boarding bridge hydraulic system was directly converted into thermal energy during the descending process,which was not well recycled and utilized,resulting in the heating of the system and affecting the service performance and life of the system.In view of this,this paper proposes a kind of hydraulic cylinder which is driven by energy recovery in the descending process of main hydraulic cylinder and energy release in the ascending process through accumulator.The simulation results show that the accumulator energy recovery system achieves a certain energy recovery effect,the energy saving effect is relatively significant,and the energy loss is also reduced.The conclusion is meaningful to the optimal design of the hydraulic system of the boarding bridge.
