Product Introduction
The MS02 axial tension compression rod internal force testing experimental device is a specialized teaching instrument used in material mechanics to deeply study the distribution law of internal forces in rods. This device utilizes a multi-channel strain measurement system, which not only focuses on the overall stress, but also emphasizes high-precision quantitative analysis of the local stress/strain distribution non-uniformity near the load application point and the section mutation. As an ideal platform for verifying the Saint Venant principle, it can intuitively demonstrate the attenuation process of the "end effect" and the mechanism of stress concentration, thereby revealing the applicability and limitations of the "plane hypothesis" in theoretical mechanics. By equipping various specialized specimens (such as perforated, notched, or variable cross-section rods) and eccentric loading mechanisms, this deviceisusedtoverifythesuperpositionprinciple,measuretheelasticmodulusandPoisson'sratioofmaterials,andexplorethe neutral axis migration law under eccentric tension and compression. It is a core teachingequipment for cultivating students' micro stress analysis ability and engineering safety awareness.
Experimental feature
1
Verify the Saint Venant principle: the core teaching function of this device
2
Research on stress concentration: Observing the phenomenon of strain surge at geometric discontinuities through specimens with holes, notches, or cross-sectional discontinuities
3
Measurement of axial tensile and compressive strain distribution: Multiple measuring points are arranged along the axis direction of the rod to record the strain gradient from the loading end to the stable zone
4
Eccentric tension compression experiment: Verify the superposition principle by separating the axial force component and bending moment component through strain gauge readings
5
Accurate determination of elastic modulus E and Poisson's ratio of materials: In the stress uniform region, using longitudinal and transverse strain gauge data, calculate the E and μ of the material
