The present invention discloses a portable comprehensive mechanical demonstrator which comprises a base (1), a fixed frame (2), a sample rod (3), at least six strain gauges (20), a force applying device, a signal processing circuit for processing the strain gauges (20), a computer and a projection device. The at least six strain gauges (20) are installed on the sample rod (3) and are electrically connected to the input end of the signal processing circuit. The output end of the signal processing circuit is electrically connected to the computer which is electrically connected to the projection device. The fixed frame (2) and the force applying device are installed on the base (1). The force applying device is installed on the fixed frame (2). The lower end of the sample rod (3) is fixed on the base (1). The upper end of the sample rod (3) is fixed on the fixed frame (2). The portable comprehensive mechanical demonstrator can test three forces at the same time and has the advantages of small size and light weight.
Description
technical field [0001] The invention relates to the technical field of mechanics measurement teaching, in particular to a portable comprehensive mechanics demonstration instrument. Background technique [0002] Mechanics instruments for teaching are instruments that measure and record force. At present, the mechanics demonstrator used for teaching can only test one kind of force, that is, it can only measure tensile force and compressive force, or it can only measure bending force, or it can only measure torsion force. If you need to measure the above three forces, you need to carry multiple instruments, which is very inconvenient. At the same time, the purchase of multiple instruments will greatly increase the financial burden of the school. In addition, the above-mentioned mechanics demonstrator also has the disadvantages of large volume and heavy weight. Therefore, based on the above reasons, there is an urgent need for a mechanical demonstration instrument that can te...
