The impact and flutter analysis and control of wind power spindle forging is to study the impact and flutter problems that may occur in the working process of wind power spindle forging, and adopt corresponding analysis and control strategies to reduce or eliminate these problems.
In the process of wind turbine operation, the main shaft forging will bear the impact and periodic variable load due to the action of wind load and rotating force. These loads can cause spindle forgings to flutter, that is, to vibrate at their natural frequency, and can have an impact on the safety and reliability of wind turbines. Therefore, it is necessary to analyze and control the impact and flutter of the spindle forging.
Impact analysis mainly analyzes the stress and deformation of spindle forgings under external impact or transient load by means of structural dynamics analysis method. By analyzing the response of the spindle forgings, the impact resistance of the spindle forgings can be predicted in advance, and the corresponding measures can be determined according to the analysis results, such as optimizing the geometry of the spindle forgings, increasing the strength of the material, or enhancing its impact resistance by improving the support structure.
Flutter analysis is to study the possible self-excited vibration of spindle forgings near the operating frequency by vibration analysis method. By analyzing the natural frequency, damping ratio and bearing capacity of spindle forgings, the risk of flutter can be evaluated and the corresponding control strategy can be adopted. Common control strategies include increasing damping, adjusting system stiffness, optimizing support structure design, etc. In addition, the dynamic observation data of spindle forging can also be used to monitor its vibration in real time and take timely measures to control flutter.
The impact and flutter analysis and control of wind power spindle forging is a complex engineering problem, which requires comprehensive consideration of many factors, such as wind turbine working conditions, environmental loads, structural materials and design. Through the method of theoretical analysis, numerical simulation and test verification, the impact and flutter of spindle forging can be deeply studied, and scientific and reasonable control measures can be put forward to ensure the safe operation and life of wind turbine.
