摘要

本研究目的在於分析前人所設計的壓縮空氣推動液壓馬達系統，並針對其油路及控制方式進行改善。在本研究中，重新分配前人所設計油路中的閥件，以減少管路耗損，並探討蓄壓器對系統之影響。透過節流閥及氣動球閥控制進入蓄壓器之流量，接著調整其預壓以得到更佳的效率。在控制方法改良方面，加入新的控制相位，並改寫控制程式，以達到節省電力的需求。除此之外，本研究比較新油路系統與舊油路系統差異，並以高壓/低壓、膨脹/等壓四種不同操作方式量測系統效率。

The purpose of this research is to redesign the compressed air driven hydraulic motor system which is designed in the former research and improve the oil line and control method. In this research, the valves in the piping system are rearranged to reduce the energy loss. The influence of the accumulators is also discussed. The use of the flow control valve and pneumatic ball valve controls the flow into the accumulator and adjusts the preload of accumulator to achieve better efficiency. To improve the control method, the system is added a new control phase and the control code are designed to decrease the consumption of power. Besides, the difference between the new piping system and old piping system is compared and measure the efficiency of high pressure/low pressure、constant pressure/expansion operations.
