Product Introduction
The MST12 temperature variation cantilever structure deformation and internal force testing experimental device is a specialized equipment used in structural mechanics experiments to study the influence of temperature effects on statically indeterminate structures.
Temperature changes in statically indeterminate structures only cause deformation and do not generate internal forces; However, in statically indeterminate structures, excessive constraints limit the free expansion or rotation of the structure, resulting in significant self stress and additional internal forces caused by temperature changes. This device simulates the temperature field and measures the internal forces (stresses) and displacements of statically and statically indeterminatestructuresundertemperaturechangesthroughsensormeasurements; Strain and displacement testing of members or structures under differenttemperature differences.
Experimental feature
1
The essential difference in demonstrating temperature effects: ①Static state: Adjust the structure to a static cantilever beam, apply temperature changes, measure its free deformation (elongation, bending), and verify that no internal forces are generated. Ultra static state: Add additional constraints (such as fixing the free end or adding elastic support), apply the same temperature change, measure the generated constraint reaction force and internal bending moment, and verify the generation of internal forces
2
Measure temperature internal force (self stress): ①Quantitatively measure the support reaction force and cross-sectional internal force caused by temperature gradient (internal and external temperature difference) or uniform temperature change. ②Verify the free terms in the force method equation
3
Measurement of thermal deformation curve: Record the deflection curve of the beam under temperature and compare it with the theoretically calculated deformation shape
4
Limitations of verifying the superposition principle: Enable students to understand the similarities and differences between temperature loads and mechanical loads in the analysis of statically indeterminate structures
