为了提高三轴液压飞行模拟转台的低速性能,近年来,南京航空学院与303所、173厂研制成功了Y CM型液压伺服马达。 Y CM型液压伺服马达鉴定会于1980年12月22日至12月26日在南航召开。会议领导小组和技术鉴定小组认为:该系列马达结构新颖,性能良好,调速范围宽,起动压差低,动态性能好(其自振频率可达300赫芝以上),它特别适于在高性能的电液伺服系统中作为执行元件使用,经使用证明调速比可达40万以上。
In order to improve the low-speed performance of the three-axis hydraulic flight simulator, in recent years, Nanjing Aeronautical Institute and the 303, 173 factory successfully developed the Y CM hydraulic servo motor. Y CM hydraulic servo motor identification will be December 22, 1980 to December 26 held in China Southern Airlines. The meeting leading group and technical appraisal team think: This series motor has the advantages of novel structure, good performance, wide speed range, low starting differential pressure and good dynamic performance (the natural frequency can reach above 300 Hertz) Performance of the electro-hydraulic servo system as the implementation of the use of components, the use of proof speed up to 400,000 or more.
