| 英文摘要 | This paper presents a new strategy to study the vibration response of antenna pitch rotor system under wind load. Taking the pitch rotation mechanism of large reflector antenna as the research object, the three-dimensional model of rotor system is established to study the dynamic behavior of pitch rotation of large aperture antenna under wind load. In this study, the antenna pitch system is regarded as a disk rotor, which acts on the bearing installed flexibly. Considering the magnitude of wind load, gyroscopic effect and elastic coupling, a six degree of freedom bearing rotor dynamic model is established based on Newtons second law, and the differential equation of the system is derived. The mathematical model is solved by numerical method in MATLAB, based on this model, according to the wind load coefficient measured in the wind tunnel experiment, the vibration response of the bearing rotor system under different wind loads is studied under the variable conditions of 10m/s, 18m/s and 25m/s, and the effects of wind speed, support stiffness and elastic modulus on the vibration characteristics of the rotor are obtained. This method provides a new idea for studying the vibration characteristics of antenna pitch system under wind load. 2022, Science Press. |
