In the long run of wind power spindle forging, due to complex working conditions and loads, there may be wear and fatigue fracture phenomena. Therefore, it is of great significance to study the wear and fatigue fracture mechanism for improving the reliability and life of spindle forgings.
Wear mechanism research:
Wear type: Through the actual use of observation and experimental research, analysis of the main shaft forging may appear wear types, such as abrasive wear, wear wear, fatigue wear, etc.
Working condition analysis: Analyze the influence of the working environment, lubrication conditions, load characteristics and other factors on the wear of the spindle forging.
Material selection: Evaluate the hardness and anti-wear properties of forging materials, and study the influence of different materials on the wear mechanism.
Research on fatigue fracture mechanism:
Stress analysis: By means of finite element analysis or test measurement, determine the stress state of the spindle forging under the actual working state, including the stress distribution under different working conditions such as static load and dynamic load.
Crack detection: Using non-destructive detection technology, crack detection of spindle forgings is carried out to understand the shape, distribution and size of cracks.
Material fatigue performance evaluation: fatigue strength, fatigue life and fatigue crack propagation rate of spindle forging materials are obtained through fatigue test, which provides basic data for the study of fatigue fracture mechanism.
Fatigue fracture analysis: Combined with the stress and crack parameters, using the theory of fracture mechanics, the fatigue fracture behavior of the spindle forging is analyzed, and various factors causing fracture are explored.
The above are the general steps and contents of the research on wear and fatigue fracture mechanism of wind power spindle forging. Through in-depth research and analysis, it can provide scientific basis for the design, manufacture and operation of the spindle forging, and then optimize the design, improve the process, and improve the reliability and service life of the product.
