摘要
在泵控差动缸系统中,无杆腔油液体积是有杆腔油液体积和充入蓄能器的油液体积之和,其中蓄能器起到了平衡油液体积外和动势能的回收利用的作用。考虑到蓄能器的充放油为非线性的,且工程机械的工况比较复杂,需要对不同工况下的蓄能器进行分析,该文仿真研究发现负载在不超过满载情况时,压力的变化规律与负载关系密切,与实际充放油做的功并无很直接的关系。蓄能器的效率随负载增加而增加,进一步说明了其对系统具有节能作用。
In the pump control differential cylinder system, rodless cavity oil volume is antrum oil volume and filling the oil volume of accumulator, the accumulator has played a balance oil volume and emf can recycling.Considering the filling oil drain accumulator is nonlinear,and the operation condition of the engineering machinery is more complex, need to the accumulator is analyzed under different working conditions, in this paper, simulation study has found that the load is less than the full load condition, close to load, and the change rule of stress and the actual filling oil drain to do the work, there is no direct relationship.Accumulator efficiency increases with the increase of load, and further illustrates the system energy saving effect.
