The performance test of agricultural machinery forgings is an important part of ensuring its quality and reliability. The following are some commonly used performance test methods for agricultural machinery forgings: Strength test: Through tensile, compression, bending and other mechanical tests for forgings, to assess their ability to withstand external loads. Common test methods include tensile test, compression test and bending test. Hardness test: Determine the hardness index of forgings, commonly used test methods are Brinell hardness, Rockwell hardness and Vickers hardness. Impact toughness test: To evaluate the rupture resistance of forgings under impact or high-speed loads, usually using impact testing machines for impact tests. Metallographic structure detection: Through metallographic microscope observation and microstructure analysis of forgings, judge the grain structure, phase ratio and internal defects of forgings. Fatigue life test: simulate the cyclic load conditions of forgings during operation, and test the fatigue life and fatigue strength of forgings by constantly applying variable amplitude load. Corrosion performance test: To evaluate the corrosion resistance of forgings in a specific environment, the commonly used test methods are salt spray test, wet heat test and acid and alkali corrosion test. Dimensional measurement: The dimensional accuracy and geometry of the forging are measured to ensure that they conform to the design requirements. The above are some commonly used agricultural forging performance test methods, the specific selection of which test methods need to be determined according to the specific forging type, application scenarios and design requirements.
