Plasticity deformation analysis and optimization of wind power spindle forgings

Wind power spindle forging is a key component responsible for bearing the rotor torque of the wind turbine, and its reliability and performance directly affect the efficiency and safe operation of the whole wind power system. In the process of design and manufacture, the analysis and optimization of the plasticity and deformation of the spindle forging can improve its strength and durability and ensure its stable operation.

Firstly, the plasticity deformation of wind power spindle forgings is analyzed in order to determine the degree of deformation and its influence on the material and structural properties. Plasticity deformation analysis mainly includes the following aspects:

  1. Bending deformation analysis: Through numerical simulation or experimental test, the bending deformation of the spindle forging under load is analyzed to determine its maximum bending degree and deformation area.
  2. Torsional deformation analysis: The main shaft forging will produce torsional deformation under the action of torsional torque, and carry out mechanical analysis to calculate the maximum torsion Angle and deformation range.
  3. Yield deformation analysis: The main shaft forging under the force, there may be a local or overall yield phenomenon, the need for detailed analysis to determine the yield point of the material and its impact on the strength of the structure.

Through the analysis of plasticity deformation, we can understand the stress and deformation degree of the spindle forging in the actual work, and provide data and basis for the subsequent optimization.

Secondly, on the basis of plasticity deformation analysis, optimization design can be carried out to improve the strength and durability of spindle forgings. The method of optimizing design includes but is not limited to the following aspects:

  1. Material selection optimization: According to the stress and deformation characteristics of the spindle forging, select the appropriate materials, such as high-strength alloy steel, fatigue resistant steel, etc., to meet the expected strength and durability requirements.
  2. Structural shape optimization: Through parametric design and simulation analysis, the structural shape of the spindle forging is optimized to improve its mechanical performance and reduce the degree of deformation. For example, measures such as increasing the beam-column structure and setting reinforcing bars can effectively improve the stiffness and stability of the spindle forgings.
  3. Processing optimization: Considering the deformation characteristics of the spindle forgings in the forging and heat treatment process, the forging temperature, pressure and heat treatment process parameters are optimized to control the deformation and ensure that the comprehensive performance of the material meets the design requirements.

In the process of optimization design, software tools such as CAD and CAE can be used for simulation analysis and optimization verification to ensure the effectiveness and feasibility of the design scheme.

To sum up, plasticity deformation analysis and optimal design of wind power spindle forgings are important links to ensure its strength and durability. Through reasonable analysis and optimization, the performance and reliability of spindle forging can be improved, its service life can be extended, and the safe operation of wind power generation system can be guaranteed.
