Abstract
In order to solve the difficulties of dynamic strain measurement of rotor blades impacted by bird,a method based on on-line detection and high-speed temporary storage is put forward.Through the real-time online detection,the strain data of bird impact in the whole process is collected and stored in a non-volatile SRAM.A multi-channel dynamic strain measurement system is designed mainly,including the detection and storage unit and the ground auxiliary device,which can meet the requirements of accuracy and speed,and realize the functions of on-line detection,high-speed storage and wireless data transmission.The tests indicate that the system has high accuracy and can detect the bird impact in real-time,and the speed of collection and storage is 200 kHz with 6 channels,and the test is convenient by using radio communication,which satisfies the dynamic strain measurement of rotor blades impacted by bird.关键词
