阀泵并联变模式调速实验系统设计
|
摘要
为了实现大功率液压马达调试系统低速平稳快速启停,同时较好地解决液压马达调速系统效率高和响应快的矛盾,设计一种阀泵并联变模式液压马达调速系统,并利用LabVIEW软件完成了系统实验台的监控和数据采集。结果表明:该液压马达调速系统具有较好的低速稳定性,对负载扰动有较强的鲁棒性,调速效果比较理想。
In order to achieve low-speed performance of high power hydraulic motor speed system as well as to balance the conflict between efficiency and response, a valve-pump parallel control system for hydraulic motor speed regulation was proposed. LabVIEW was used to monitor and collect data of the experimental system. The results show the hydraulic motor speed system has preferable performance on low speed stability, and strong robustness on load disturbance, thus offer a good option for speed.
