Abstract

Water hydraulic fluid switching transmission (FST) has lower environmental load and lower energy loss in valves for using only ON/OFF valves. In addition, improvement of transmission efficiency can be expected by using accumulator as the second driving source and making use of waste energy by energy recovering action. This paper concerned with experimental results and a design of simulator of the FST system. First, it was shown from experimental results that the error rate was within 5 percent and the recovered energy during the deceleration phase was more than 25-38% of the kinetic energy of the load. Next, the FST simulator was developed for designing the key parameters to achieve higher transmission efficiency. As a result, the effects of design parameters of FST system were clarified and design standard of water hydraulic FST was established.
水液压换向传动的能效研究
水液压流体开关传动(FST)具有较低的环境负荷和较低的能量损失,仅使用ON/OFF阀。此外,采用蓄能器作为第二驱动源,利用能量回收动作来利用废弃能量,可以提高传动效率。本文介绍了FST系统的实验结果和模拟器的设计。首先,实验结果表明,该方法的误差率在5%以内,减速阶段的回收能量大于负载动能的25-38%。其次,开发了FST模拟器,对关键参数进行了设计,以实现更高的传输效率。阐明了FST系统设计参数的影响,建立了水力FST的设计标准。
