Multifunctional Mechanics Experimental System The multifunctional mechanics comprehensive experimental system is an experimental device developed by the Department of Mechanics of Southwest Jiaotong University based on years of mechanical experiment teaching experience and requirements, and jointly launched by the Land Technology Corporation. The system is composed of software and hardware, and has realized digitization and intelligence. Contains a variety of experimental programs, a wide range of options. It is conducive to the parallel configuration of multiple laboratories and can form a local area network, which is convenient for students to do it by themselves. A new teaching model suitable for personalized development.

The experimental device of this system includes:

(1) Elastic compression bar experiment: real abdominal compression gangue and combined compression bar (simulated lattice column) restraint and bearing capacity.

(2) Variable-angle truss unit experiment: reveal the relationship between structural configuration and its mechanical behavior, linear and nonlinear.

(3) Rigid frame and truss test: reveal the correlation difference between the structure calculation sketch and the actual structure.

(4) Composite beam experiment: Taste the complexity of the contact problem in mechanics.

(5) Curved beam and arch experiment: reveal the disparity between statically and ultra statically determinate structures.

(6) Determination of the mechanical properties of self-selected materials: expand the range of experimental materials and broaden the knowledge of materials.

(7) Thin-walled rod bending experiment: revealing the disparity between open and closed thin-walled rods.

Elastic pressure bar experiment

1. Stranded ends at both ends

2. One end is fixed and one end is twisted

3. One end free, one end twisted

4. One end slide, one end twisted

5. Fixed at both ends

6. One end is free and one end is fixed

7. Stranded support at one end and elastic support at one end

8. One end is fixed and one end is elastically supported

9. One end is free, one end is elastically supported

10. One end slide, one end elastic support

11. Twisted ends at both ends, intermediate support

Experiment of curved beam and arch

Experiments can be done separately:

Simple Support Curved Beam (Static)

Two-hinge arch (once statically determined)

Hingeless arch (three times statically indeterminate)

Experiments in two different states, small displacement and large displacement, can also be done.
