基于PAC的零航速减摇鳍升力测量系统研究

Research on lift measurement system of zero-speed fin stabilizers base on PAC

零航速减摇鳍是一种新型减摇装置,其升力产生机理、控制策略都与传统减摇鳍不同。通过对现有实验设备数据采集和控制系统的改进,建立一套适合零航速减摇鳍控制系统特点和实验要求的实验室升力检测系统。升力检测系统包括基于压阻式升力传感器的检测元件和基于PAC的数据采集及记录的控制系统。可用于分析和验证零航速减摇鳍的升力理论模型,为工程实验提供有价值的信息。

Zero-speed fin stabilizer is a new kind of anti-roll system, the lift and control method of zero-speed fin stabilizers is different from traditional fin stabilizers. The lift measurement system which is suitable for zero-speed fin stabilizers is built by improving existed experiment system and control system. The lift measurement system includes lift sensor and data collecting and analyzing control system based on PAC （PC based PLC）. The system can be used to analyze and test the lift model of zero-speed fin stabilizers and supply a useful data for engineering experiment.
