  • A continuous scanning laser Doppler vibration test method for operational deflection shape (ODS) of the thin-walled cylindrical outer surface was proposed and applied to vibration test of a cylinder. The rotating platform and motor control were introduced into the laser continuous scanning, and a motor control algorithm matching the laser continuous scan path was developed. The continuous scanning laser vibration test was applied to cylinder structure. And the cylinder laser continuous scanning test was performed on a cylinder structure and the first five orders mode within 500 Hz were obtained. The correlation with the results from the commercial laser discrete scanning modal test was basically above 0.96, demonstrating the feasibility and accuracy of cylinder laser continuous scanning laser Doppler vibration test. The cylinder continuous scanning laser Doppler vibration test, with advantage of high spatial resolution, efficient and effective test, shows certain guiding significance and practical value for further application in actual structure.
