摘要
本文从液压系统的组成、结构及工作工况特点出发,对液压系统过渡状态下非恒定流的频率特性提出了适合于计算机处理的数值计算模型。通过应用实例,数值计算结果较好地吻合了实测结果,从而为液压系统的计算机辅助设计、性能评估与预测,提供了快速、经济、有效的方法。
Accoding to the composition , structure and working characteristics of hydraulic sys-tem, numerical analysis method, suitable for computer process, for the characteristics of unsteady flow in frequency domain of hydraulic system in a state of transition were established. With their application cases, theoretical calculating results are quite identical with experimental outcomes. Therefore, a fast effective analysis method used in CAD, performance judging and foreseeing of hydraulic system was presented in this paper.
