With the rapid development of wind power industry, wind power spindle forging as one of the key components of wind power generating units, its design optimization and weight reduction research is of great significance. This paper focuses on the design optimization and weight reduction of wind power spindle forging, and discusses several common methods and technologies.
I. Design optimization method:
- Structural topology optimization: By optimizing the structural topology of the wind power spindle forging, the optimal distribution of structural materials can be achieved, reducing weight and maintaining sufficient strength and rigidity. Topology optimization method uses finite element analysis and numerical optimization algorithm to reduce unnecessary materials and achieve weight reduction by gradually adjusting the structure shape.
- Material optimization: Choosing the right material is crucial for the design optimization and weight reduction of wind power spindle forging. By selecting high-strength, high-toughness and lightweight engineering materials, such as high-strength steel, aluminum alloy, etc., the dead weight of the spindle forging can be greatly reduced and the overall performance can be improved.
- Parametric design and optimization: CAD software is used to establish the three-dimensional model of wind power spindle forging, and relevant parameters are centralized processing, and multi-objective optimization is achieved through parametric design and optimization methods. This method can quickly generate different design schemes and screen out the best design schemes.
Two, weight reduction technology:
- Hollow structure design: The internal part of the wind power spindle forging adopts hollow structure design, which can reduce its own weight and improve its strength. The proper layout of the internal cavity reduces the amount of material used while maintaining adequate stiffness and mechanical properties.
- Material substitution and thin-wall design: The use of lightweight materials instead of traditional materials, and the use of thin-wall design to reduce the use of materials, so as to achieve weight reduction. At the same time, attention should be paid to the design under the premise of ensuring strength and stiffness to ensure safety and reliability.
- Structural optimization and reinforcement: Through the optimization and reinforcement of the structure of the wind power spindle forging, it is more stable and reliable when bearing wind loads and rotating motion. Appropriate addition of some structural parts, improve the local stress distribution, improve the overall mechanical performance, reduce the use of excess materials.
Research on design optimization and weight reduction of wind power spindle forging is an indispensable subject in wind power industry. By adopting reasonable design method and weight reduction technology, the dead weight of wind power spindle forging can be reduced, and the overall efficiency and life can be improved. In the future, we should continue to strengthen technological innovation and research, and constantly propose more effective design optimization and weight reduction methods to promote the development and application of wind power spindle forgings.
