1.7 Mechanical assembly and bench assembly virtual simulation software (provide copyright certificate and on-site demonstration): This software is developed based on unity3d, with 6 levels of image quality optional, and has reducers, shaft system structure design and virtual disassembly and assembly, common mechanical mechanism design and simulation, mechanism resource library, typical mechanical mechanism (virtual disassembly and assembly of gasoline engine), the software is an integral software, not a separate resource.
A. The reducer design and virtual disassembly and assembly interface can select worm bevel gear reducer, two-stage unfolded cylindrical gear reducer, bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, and one-stage cylindrical gear reducer.
Worm bevel gear reducer: After entering the software, the assembly content will be played automatically, and each step in the video has text descriptions.
Secondary unfolded cylindrical gear reducer: After entering the software, the content will be played in the form of a video. The video content should include: part name (scan the QR code to see the part name), disassembly demonstration (including disassembly, assembly), virtual disassembly (including the whole, low-speed shaft, medium-speed shaft, high-speed shaft, box cover, box seat)
bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, first-stage cylindrical gear reducer: click to enter and automatically jump to the edrawings interface, modelAll of them are 3D models. By clicking on the parts, the names of the parts are displayed. They can be rotated 360°, enlarged, reduced, and translated. At the same time, the entire reducer can be disassembled and assembled by moving the parts function. At the same time, the home button can be selected to return to the initial state of the reducer. The bevel gear reducer and the first-level cylindrical gear reducer have added the function of inserting cross sections, and the cross sections can be freely dragged to observe the internal structure of the reducer.
B. The design of the shaft structure and the virtual disassembly and assembly interface can
select parts recognition, disassembly and assembly demonstration, and actual combat operation. 1. Part recognition: The 3D models and part names of helical gears, holeless end covers, couplings, coupling keys, shafts, gear keys, holed end covers, sleeves, and deep groove ball bearings are built in. Any part can be rotated 360°.

When the mouse is moved to a cert*n part position (except the base and the bearing seat), the part is automatically enlarged and the part name is displayed. There are disassembly and assembly buttons. The function is automatically completed by the software to disassemble and assemble the shaft structure. All 3D scenes can be rotated 360°, enlarged, reduced, and translated.
3. Actual operation: The three-dimensional parts are neatly placed on the desktop. Students manually select the corresponding parts and move them to the shaft structure. The parts can only be installed when the placement order and position are correct. There is a restart button to facilitate students to repeat the virtual experiment. When the mouse moves to a cert*n part position (except the base and the bearing seat), the part is automatically enlarged and the part name is displayed.

The crankcase assembly and disassembly demonstration and the valve system assembly and disassembly demonstration are equipped with disassembly buttons, assembly buttons, restart buttons, and decomposition observation buttons. When the mouse moves to a cert*n part position, the part is automatically enlarged and the part name is displayed. The function is automatically completed by the software to disassemble and assemble the shaft system structure. When the decomposition observation button is used, the three-dimensional model of the crankcase or valve system automatically displays an exploded view, which can be rotated 360° in all directions, enlarged, reduced, and translated.
2. The three-dimensional parts of the crankcase virtual assembly and the valve system virtual assembly are neatly placed on the desktop. Students manually select the corresponding parts and move them to the mechanism. The parts can only be installed when the placement order is correct and the position is correct. There is a restart button to facilitate students to re-conduct virtual experiments. When you move the mouse to cert*n parts, the part names are automatically displayed.
