1. Functions and features:
The bolt group connection experimental device can conduct experiments on static and dynamic stress, deformation, stiffness, axial load, pre-tightening force, etc. of bolts.
Special testing and analysis software can perform relevant detection and comparison on static and dynamic bolts. Measured and simulated curves, the curves can be printed.
All tested components adopt full-bridge test circuits, and each str*n test structure is stable, repeatable, and high-precision.
Using a single-phase AC motor (220V power supply), it is convenient to start the motor for static and dynamic bolt experiments.
The special test analysis software has multimedia teaching functions. Students can conduct experiments independently through the experimental instructions in the software, and edit test reports through the software.
2. Experimental purpose
1. Understand the stress of each part of the bolt connection during the tightening process.
2. Calculate the relative stiffness of the bolts and draw the stress deformation diagram of the bolt connection.
3. Verify the deformation rules of the pre-tightened bolt connection when subjected to axial working load, and its impact on the total tension of the bolt.
4. Through the dynamic load experiment of bolts, change the relative stiffness of the bolt connection and observe the changes in the variable stress amplitude of the bolt to verify various measures to improve the strength of the bolt connection.

7. Mechanical tr*ning safety education virtual simulation software: using 3D virtual simulation technology, without relying on other third-party platforms (such as Flash, Unity, etc.) ), the interface is vivid and beautiful, easy to learn and use, which can improve teachers’ interest in teaching and students’ learning, and deepen students’ understanding and application of plane, space, and gear system knowledge. The software vividly displays the disassembly and assembly process of plane, space, gear tr*n and other modules through three-dimensional disassembly animation, three-dimensional assembly animation, simulated disassembly and other methods. The model in the software can be rotated, enlarged and reduced by students in all directions to view the assembly project. For det*ls, students can disassemble and assemble manually or disassemble and assemble by themselves through the software.
The following functions can be realized:
basic knowledge and introduction of planar mechanisms
, virtual disassembly, three-dimensional animation demonstration, and exploded view display of
planar mechanisms. Basic knowledge and introduction of
space mechanisms, virtual disassembly, three-dimensional animation demonstration, and exploded view display of space mechanisms.
Wheel tr*n mechanisms Basic knowledge and introduction to
the gear tr*n mechanism. Virtual disassembly, three-dimensional animation demonstration, and exploded view display.
Save and read assembly records.
Display of single parts of each mechanism.
Calculation of plane degrees of freedom.
8. Electrical safety and electric shock first *d simulation teaching software
The software uses a combination of two-dimensional and three-dimensional virtual images to teach students the safety and first *d methods of using electricity. The software includes single-phase electric shock, two-phase electric shock, step electric shock, low-voltage electric shock first *d, high-voltage electric shock first *d, artificial respiration first *d, Principles of hand-holding breathing rescue method, chest cardiac compression and other protective methods are expl*ned and taught, and the principles of single-phase electric shock are divided into rep*ring live disconnection, rep*ring socket electric shock, and outdoor electric shock. The teaching of low-voltage electric shock and high-voltage electric shock m*nly expl*ns and demonstrates to students how to rescue people who are suffering from low-voltage electric shock or high-voltage electric shock. Artificial respiration rescue method, hand-holding breathing rescue method, and chest cardiac compression rescue method are demonstrated using 3D virtual simulation technology. After rendering and Polish it to make the model look like the real part and look realistic. Through practical tr*ning, students can be educated on the safe use of electricity in the tr*ning room, improve students' safety awareness, and enable students to learn some self-rescue methods, so that students can take cert*n safety measures to protect themselves when encountering danger, and become familiar with various Causes of electrical accidents and practical measures to deal with them to reduce the occurrence of electrical accidents.
