Virtual simulation teaching system Mechanical tr*ning safety education virtual simulation software: This software is developed based on unity3d. The software adopts the form of three-dimensional roaming. It can control movement through the keyboard and the mouse to control the direction of the lens. It is equipped with mechanical safety distance experiments and mechanical safety protection devices. Experiment and basic assessment of mechanical safety protection design. When the experiment is in progress, the three-dimensional roaming screen uses arrows and footprints to prompt the user to move to the experimental location. The circle around the mechanical object displays the working radius. The experimental process is accompanied by a dialog box reminder of the three-dimensional robot. A. The content of the mechanical safety distance experiment includes the safety distance experiment to prevent upper and lower limbs from touching the danger zone (divided into two fence heights and opening sizes). After selecting to enter, GB23821-2009 "Mechanical Safety to Prevent Upper and Lower Limbs from Touching the Danger Zone" pops up in front of the camera. "Safe Distance" requirements, error demonstration: The experimental process is that after the human body enters the working radius of the mechanical object and is injured, the red screen and voice prompts that the human body has received mechanical damage, and returns to the original position and conducts the next experiment. The last step is the correct approach. B. Mechanical safety protection device experiments are divided into safety interlock switches, safety light curt*ns, safety mats, safety laser scanners and other protection device experiments. Optional categories (safety input, safety control, safety output, others), manufacturers, products List (safety interlock switch, safety light curt*n, safety mat, safety laser scanner, safety controller, safety relay, safety guardr*l). There is a blue flashing frame reminder at the installation location. Experimental process: select the safety guardr*l and install it, select the safety interlock switch (or select the safety light curt*n, safety mat, safety laser scanner) and install it, select the safety controller and install it in the electrical control box , select the safety relay and install it in the electrical control box, click the start button on the electrical control box. If you enter a dangerous area, the system will sound an alarm and the mechanical object will stop working. Select the reset button on the electrical control box to stop. C. The basic assessment of mechanical safety protection design requires the completion of the installation of the mechanical safety system, and the correct installation of safety guardr*ls, safety interlock switches, safety light curt*ns, safety mats, safety laser scanners, safety controllers, safety relays, 24V power supplies, signal lights and Emergency stop button, the assessment is divided into ten assessment points. Some assessment points have 3 options, which are freely chosen by the students. After selecting the final 10 assessment points, submit for confirmation, and the system will automatically obt*n the total score and the score of each assessment point. . D. The software must be on the same platform as a whole and cannot be displayed as separate resources. E.

The models are all three-dimensional models. By clicking on the parts, the names of the parts are displayed, and the 360° view is av*lable Rotate, zoom in, zoom out, pan, and move parts to disassemble and assemble the entire reducer. At the same time, you can select the home button to return to the original state of the reducer. The bevel gear reducer and the first-stage cylindrical gear reducer have added the function of inserting a cross section, and the cross section can be freely dragged to observe the internal structure of the reducer.
