Environmental adaptability and reliability evaluation of copper forgings of agricultural machinery is an important research subject, which is related to the service life and safety of agricultural machinery. The following will introduce the main contents and methods of environmental adaptability and reliability assessment of copper forgings of agricultural machinery.
- Environmental adaptability assessment:
Copper forgings of agricultural machinery work in harsh environment such as farmland, and need to have good adaptability. Environmental adaptability assessment mainly includes the following aspects:
- Mechanical load evaluation: Through the simulation of the working load of agricultural machinery, static and dynamic loading tests are carried out to analyze the strength, stiffness and fatigue life of copper forgings of agricultural machinery. At the same time, it is also necessary to consider the differences in the load of different crops and soil conditions.
- Corrosion environment assessment: Copper forgings of agricultural machinery are in a humid environment for a long time and are susceptible to corrosion. The corrosion resistance and oxidation resistance of copper forgings for agricultural machinery were evaluated by means of wet heat test and salt spray corrosion test.
Temperature change assessment: Copper forgings of agricultural machinery will be affected by temperature changes during the working process, which may cause size changes and mechanical property losses. The dimensional stability and mechanical properties of agricultural copper forgings under temperature change were evaluated by thermal expansion test and low temperature test.
- Reliability assessment:
Reliability assessment is mainly a comprehensive analysis and assessment of the design, materials and manufacturing process of agricultural copper forgings to improve their service life and reliability.
- Failure mode and influence analysis: analysis of failure mode of copper forgings of agricultural machinery, including fatigue fracture, corrosion failure, etc. Evaluate the impact of different failure modes on performance, and provide basis for subsequent improvement.
- Life prediction and reliability design: Using reliability engineering methods, life prediction and reliability design of agricultural copper forgings are carried out to determine their service life and reliability level under given conditions.
- Fault diagnosis and maintenance strategy: Establish a fault diagnosis system for copper forgings of agricultural machinery, discover potential problems in time and take appropriate maintenance strategies through monitoring and analyzing equipment status, so as to improve the reliability and service life of copper forgings of agricultural machinery.
- Improvement measures:
Based on the findings of the environmental adaptability and reliability assessment, the following improvements can be taken:
- Material optimization: Select alloy materials with corrosion resistance and fatigue resistance to improve the service life and corrosion resistance of agricultural copper forgings.
- Design optimization: fully consider the stress conditions of agricultural copper forgings under different working conditions, reasonably design the structural form and size, and reduce the risk of stress concentration and fatigue fracture.
- Manufacturing process improvement: Optimize the manufacturing process of agricultural copper forgings, improve their dimensional accuracy and surface quality, in order to reduce the impact of manufacturing defects on performance.
- Maintenance management: Establish a scientific and reasonable maintenance management system, regularly check and maintain agricultural machinery copper forgings, timely discover hidden dangers and take appropriate maintenance measures to extend their service life.
Through the above environmental adaptability and reliability evaluation research and the implementation of improvement measures, the adaptability and service life of copper forgings of agricultural machinery can be improved, and the efficient operation of agricultural machinery can be ensured.
