E: Professional Skills Comprehensive Integrated Tr--ning Virtual Simulation System

The software in the software can be rotated, magnified, reduced, and translated at 360 °. There are general interactive buttons: return, homepage, help. All virtual simulation tasks are prompted, and the software automatically hooks after a task. There is an experimental task above the tool library

1. Basic three -dimensional (XYZ space coordinate icon is automatically rotated at the XYZ space coordinate icon.)

A. Graphic stereo: The experimental steps are divided into experimental tasks (text prompt tasks) -the construction model (the model in the drag and dragging tool library to the three -projection surface system, and automatically appear the projection, there is a prompt when choosing an error) - change the attitude (by passing the passage) Click on the up, down, left and right arrows) — Select the projection (enter the answer interface, select the 3D projection map completed at this time in 6 items)

B. Cutting three -dimensional: The experimental steps are divided into experimental tasks (text prompt tasks) -the construction model (the model in the drag and drag the tool library to the three -projection surface system, and automatically display projection) -The label projection situation (for the three -dimensional projection drawing calibration , Select the corresponding labeling symbols in 14 blank fences)

C. Concerning three -dimensional: Experimental steps are divided into experimental tasks (text prompt tasks) -Dhole digging (select arbitrarily digging models, at this time, you can select any noodles in the XYZ space coordinate, the model can be switched at the same time, and a coordinate slider appears appears. According to the size of the slider, the model appears with a corresponding degree of cutting surface) -the pore diameter change (select 1-4 aperture)-rear pores-select projection (enter the answering interface, select the three-dimensional projection map completed at this time in 8 items)

2. Combination

A. Combination assembly: The experimental steps are divided into experimental tasks (text prompt tasks) -select the combination model (8 optional models) — the assembly combination (select the tool library model according to the selected model and drag the combination) - cut cutting Combination (can choose any surface in XYZ space coordinates, switch the model at the same time, and a coordinate slider appears, according to the slider displacement, the model appears with a corresponding degree of cutting) — Select the side projection (enter the answer interface, according to the known known The front and horizontal projection diagrams, select the correct side projection diagram in 3 items)

B. Combine reading: The experimental steps are divided into experimental tasks (text prompt tasks) -select the combination body section view (8 optional) — Construct a combination model (select the tool library model according to the selected model and drag the combination) - Clicply combination (can be selected in the XYZ space coordinates, the model is switched at the same time, and a coordinate slider appears. According to the slider displacement, the model appears with a corresponding degree of cutting) Known the m--n view and overwhelming view, select the correct left view in 3 items)

Elevator head tr--ning device,Bolt Group Experiment

Experimental project content:

Complete the 4 different rigid connectors and the connection of the connecting parts, dynamic force and deformation experiments of the four different rigid connections of a single tight connection bolt:

1. Static and dynamic experiments of rigid pads, no cone -free S-- Lian.

2. Rigid pads, static and dynamic experiments with cone condensation.

3. Elastic pads, static and dynamic experiments of cone -free Cylian connection.

4. Elastic pads, static and dynamic experiments with cone condensation.

5. Draw the static and dynamic curve of the force of the bolt and the stress of the connection and the deformation.

Complete the connection characteristics of the bolt group (determine the force and deformation of each bolt), and draw the static curve of the load distribution of the bolt group.

Understand the stress situation of each part in the process of tightening a single bolt

Understand the deformation of a single bolt when the static axial load is loaded.

Observe the changes in a single bolt dynamic stress amplitude to verify the measures that increase the intensity of the bolt connection.

The resistance of the resistance should be measured.
