The invention discloses a two-dimensional physical testing device for testing fatigue of a metal material, relates to the technical field of fatigue strength testing of the metal material, and solves the problems that the existing metal material is inconvenient to test on the same equipment due to different appearances, needs to be matched with various different pieces of equipment, and clamping is not convenient. The two-dimensional physical testing device for testing fatigue of the metal material comprises a connecting base, two connecting plates are arranged on one side of the connecting base, an adjusting base mechanism is arranged at the other ends of the connecting plates, and two supporting frames are arranged above the adjusting base mechanism. By arranging the connecting base, a plate testing mechanism, the adjusting base mechanism, a cylindrical part clamping mechanism and a cylindrical part testing hydraulic rod, plates and cylindrical metal parts with different sizes can be detected on the same equipment at the same time, and the working efficiency is effectively improved.
Description
technical field [0001] The invention relates to the technical field of metal material fatigue strength testing, in particular to a two-dimensional physical testing device for metal material fatigue testing. Background technique [0002] With the rapid development of social economy, fatigue strength refers to the maximum stress that the material will not be damaged under the action of infinite number of alternating loads, which is called fatigue strength or fatigue limit. The calculation of conventional fatigue strength is based on the nominal stress. It can be divided into infinite life calculation and finite life calculation. The fatigue life of parts is related to the stress and strain levels of parts. The relationship between them can be calculated by stress-life curve (σ-N curve) and strain-life curve (δ-N curve) shows. [0003] However, due to the different shapes of existing metal materials, it is inconvenient to test on the same equipment when testing, and requires t...
