摘要

为了对液压系统进行快速的能量分析，建立了一个简单的准静态仿真模型。分析的目的是确定主要的损失来源和最合适的方法来节省能源的移动起重机。对集中式和分散式液压回路进行了比较。对各种负载周期进行了分析，发现能耗和装机功率可以分别减少30%和近50%，这与负载周期有很大的关系。但是，如果泵只能在一定速度以上运行，分散可能导致能量性能的恶化。

Hydraulics Decentralization on a Mobile Crane

A simple quasi-static simulation model was developed to allow for a fast energetic analysis of hydraulic systems. The purpose of the analysis is the identification of the major sources of losses and of the most suitable approaches to save energy on a mobile crane. A comparison between a centralized and a decentralized hydraulic circuit was performed. Various load cycles were analyzed and it emerged that energy consumption and installed power can be reduced up to 30% and almost up to 50%, respectively, strongly depending on the load cycle. However, if pump operation is possible only above a certain speed, decentralization can lead to a deterioration of the energetic performance.
