【Abstract】 A set of multi function dynamic data acquisition and processing system is developed for helicopter rotor model experiments. The system features the advanced sample hold technique and repeating external trigger model in hardware design as well as the module structure in software design. The design ideas of the system are briefly instroduced and its structure and characteristic are described in detail. The application examples of the system to two different rotor model experiments have been presented. Its characteristics of fast sample rate, high accuracy and convenient operation are demonstrated. It is shown that the data acquisition and processing system is well suitable for dynamic data acquisition and analysis in helicopter rotor model experiments.更多还原
