工程机械液压系统可靠性设计分析

现代工程机械的主要工作装置大多采用液压控制技术实现，因此液压系统的可靠性往往对整机的可靠性产生很大的影响。利用系统工程理论，分析了液压系统可靠性的几个参数，定量地分析了工程机械液压系统的可靠性模型，为使系统具有高有效度，液压系统的可靠性设计和维修性设计应得以充分重视，并提出了具体措施。

Analysis of reliability design for hydraulic system of construction machinery

Most of working attachments for construction machinery are controlled by hydraulic control technology, therefore reliability of hydraulic system is of utmost importance to reliability of whole machinery. This paper analyzes several parameters of reliability for hydraulic system and the reliability model for construction machinery by means of systems engineering theory. Finally it comes to a conclusion that attention should be paid to both hydraulic system design and maintenance for the system having high - cycle efficiency and puts forward a practical step.
