【Abstract】 In order to realize the fully automatic process of the wind tunnel rotary balance test and improve the test efficiency,while ensuring the accuracy and synchronization of the test data collected,a test control mode driven by motor reducer was designed.The data signals of the balance and the motor drive circuit were extracted from the system through the slip ring.Triggered by the FPGA high-precision clock signal,the synchronization of the movement and acquisition was realized.LabVIEW platform was used to design a fully automatic test software which provides a completely automatic process solution for wind tunnel rotary balance testing.更多还原
