Three-freedom-degree minisize flapping-test measurement and control system

The invention provides a three-freedom-degree minisize flapping-test measurement and control system. In the system, through an interface adapter, a computer is connected with three motor controllers so that three minisize motors are controlled respectively. Output ends of the minisize motors are connected with a three-dimensional flapping mechanism. An output part of the three-dimensional flapping mechanism is connected with a six-component minisize force/torque sensor. The six-component minisize force/ torque sensor is directly connected with a test wing. Each of the tail parts of the minisize motors is provided with a coder. Output ends of the coders are connected with the motor controllers. Output signals of the six-component minisize force/ torque sensor are connected with a signal conditioning box. The signal conditioning box is connected with an input end of a data acquisition card after amplifying a voltage signal acquired by the six-component minisize force/ torque sensor. An output end of the data acquisition card is connected with the computer. The three-freedom-degree minisize flapping-test measurement and control system enables the wing to realize three-dimensional combination flapping of any form. The system is simple and rapid in measurement scheme and at the same time capable of acquiring a plurality of aerodynamic-force data. The system is comparatively great in data synchronization and high in test efficiency.
