AI Technical Summary
Existing tensile and bending testing machines cannot fully reflect the overall performance of the same batch of materials when testing metallic materials, especially the local performance differences caused by microstructure inhomogeneity, resulting in inaccurate test results.
A tensile bending testing machine was designed, comprising a bending testing mechanism and a tensile testing mechanism. Through components such as a lifting plate, a lifting cylinder, an adjusting motor, and an adjusting screw, multi-position testing is achieved, ensuring that metal materials in different positions can be tested and comprehensive performance data can be obtained.
Multi-location testing can accurately identify and quantify performance fluctuations in the same batch of metal materials, avoid overall component failure due to local defects, simulate actual service conditions, and provide a more realistic mechanical performance assessment.
