Description

Technical Field

[0001] This utility model relates to the field of materials testing, and more specifically, to a reaction frame structure for a high-throughput mechanical testing machine. Background Technology

[0002] Corrosion and fatigue are among the main forms of failure in structural materials, especially metallic structures. Data on material corrosion and fatigue performance obtained through testing are crucial fundamental parameters for structural safety and reliability design. Due to the numerous influencing factors and the high dispersion of experimental data, a relatively complete set of corrosion performance data for a material requires extensive testing. Similarly, fatigue performance data also exhibits high dispersion and necessitates numerous experiments. Stress is a major factor affecting material corrosion and fatigue behavior. Relatively complete corrosion and fatigue performance data for a material requires a series of corrosion and fatigue test data under various stress levels. Establishing a multi-sample stress loading test apparatus capable of simultaneously and independently applying stress loads to a large number of samples is of great significance for improving the efficiency of material corrosion and fatigue testing.

Each stress loading device corresponds one-to-one with a sample. A slot is provided on the base, which engages with the sample. Each sample corresponds one-to-one with the slot. The crossbeam includes a first main plate, on which first transverse stiffeners and first longitudinal stiffeners are provided, arranged in a "well" shape.
