Automobile airbag demonstration training device

Based on the real objects of the car --rbag and the seat belt tightrs, the composition and working process of the car --rbag and the seat belt tightness system is fully displayed.

It is suitable for the teaching needs of the school's theory and m--ntenance tr--ning of automobile --rbags and seat belts.

2. Functional characteristics

1. Real -operated car --rbags and safety belt tightening systems, fully display the composition of the car --rbag and seat belt tightrist system.

2. Manipulate the collision car, simulate the collision process of the car, simulate the --rbags from the left and right, and the --rbags are quickly inflated and expanded, and the work process of truly demonstration of the car --rbag system is truly demonstrated.

3. The teaching board panel adopts a 4mm thick corrosion resistance, strike, pollution resistance, fire prevention, and moisture -proof ** aluminum -plastic plate, sprayed on the surface by special crafts; Intuitive control circuit diagrams and physical objects, understand and analyze the working principle of the auto --rbag system.

4. Detective terminals are installed on the teaching board panel, which can directly detect the electrical signals of the circuit components of the car --rbag system on the panel, such as resistance, voltage, current, frequency signals, etc.

5. Diagnostic seats are installed on the teaching board panel, which can be connected to a dedicated or universal car decoder to read the self -diagnostic function of the --rbag control unit and clear the fault code.

6. The teaching plate panel is partially stamped with a 1.5mm cold plate stamping structure and a beautiful appearance.

7. The work of the teaching board adopts a normal 220V AC power supply, which is converted into a 12V DC power supply by transformed by the internal circuit. No battery is required to reduce the trouble of charging. The 12V DC power supply has a short circuit function.

8. Machinery assembly and fitter assembly virtual simulation software: This software is developed based on Unity3D, which can choose 6 -level image quality. It has the design and virtual disassembly of the reducer and shaft structure, the design and simulation of common mechanical mechanisms, institutional resource libraries, institutional resource libraries. Typical mechanical institutions (virtual disassembly of gasoline engines), software is an overall software, which cannot be separate resources.

Feature

2. The equipment is a self -propelled frame structure, and the feet are installed to facilitate the disassembly m--ntenance and handling of the system.

3. The bed part of this experimental device is made of all transparent and high -quality organic glass. The experimental phenomenon is clear, which is convenient for students to observe.

4. This experimental device is intuitive and stable, and has good experimental effects.

5. Device design can be observed at 360 degrees to achieve comprehensive teaching and experiments.

Device function

1. Observe the phenomenon of clustering and scattered fluidization experiments and differences between them.

2. Master the measurement method of the fluidity characteristics of fluids through the granular bed layer.

3. Measure the accumulation density and gap rate of the bed layer.

4. Determine the fluidization curve and critical fluidization of the --r bed and water bed respectively.

Design Parameters

Normally pressure, normal temperature operation.

The flow rate of the fluidized bed is 0.2m/s, the internal voltage of the fluidized bed drops 0.06-0.6kPa.

Liquid flow: 40-400L/h.

Gas flow: 2.5-25 m3/h.

Public facilities water: The device comes with a transparent water tank and connects tap water. During the experiment, the pump enters the fluidized bed and is used in a cycle.

Electric: voltage AC220V, power 1kW, standard single -phase three -line system. Each laboratory needs to be configured with 1-2 connection locations (safe and signal places).

Qi: The --r comes from a low noise fan (its own gas source).

Experimental materials: quartz sand, outer equipment: None
