| Abstract: | In the ship and offshore platform engineering practices,a rocking vibration with a large amplitude of the structure are often excited by the storm.In this paper,a method of dynamic angle measurement based on the Micro-Electronic Mechanical System （MEMS） gyroscope was studied experimentally.The zero drift phenomenon of the MEMS gyroscope was solved by the complementary filtering algorithm.Thel-DOF rocking vibration curves in the time domain and frequency domain were obtained and analyzed. |
