As a clean and renewable form of energy, wind power has attracted wide attention. As the core transmission element, the spindle forging in wind turbine undertakes the important task of converting wind energy into electric energy. However, due to the high-speed rotation of the spindle and the complex and changeable working environment, it faces increasing challenges and pressure. Therefore, it is of great practical significance and scientific value to study the durability and reliability of spindle forging.
The working environment of wind power spindle forgings The wind power spindle forgings experience complex and varied working conditions during the working process, including high-speed rotation, periodic load change, temperature change, etc. These conditions put forward severe requirements for fatigue life and durability of spindle forgings. In addition, it is also necessary to consider the influence of external factors such as particle corrosion and humidity on the spindle forging.
Factors affecting the performance of wind power spindle forgings The performance of wind power spindle forgings is affected by many factors, including material strength, toughness, hardness, lattice structure and process parameters. Reasonable selection of materials and control of process is very important to improve the performance of spindle forging. At the same time, the shape, structural design and assembly quality of the spindle forging will also affect its durability and reliability.
Experimental research and Numerical simulation methods In order to study the durability and reliability of wind power spindle forgings, a combination of experimental research and numerical simulation is adopted in this study. Through the design of loading tests under different working conditions, the stress-strain distribution and displacement changes of spindle forgings are obtained. The numerical simulation uses finite element simulation software to simulate the stress of the spindle forging under different working conditions and evaluate its fatigue life.
Reliability evaluation and improvement measures Through the analysis of test data and simulation results, combined with the reliability evaluation method, the durability and reliability of wind power spindle forging are evaluated. According to the evaluation results, a series of improvement measures are put forward, including optimizing material selection, improving process parameters, perfecting design and machining quality control, etc., in order to improve the durability and reliability of spindle forging.
Conclusion The durability and reliability of wind power spindle forging are systematically studied in this paper. Through the method of combining experimental research and numerical simulation, the key factors affecting the performance of spindle forging are deeply analyzed, and the corresponding improvement measures are put forward. The results show that the durability and reliability of wind power spindle forgings can be effectively improved by rational selection of materials, optimization of process, improvement of design and machining quality control, so as to ensure the safe operation and life of wind power generating units.
