Inside the stabilizer bar, there is a reduction mechanism and motor , which can realize two modes of control. The first is: the active transverse stabilizer bar can be separated from each other through the two halves to achieve comfortable control; the second is: the pipes in the active transverse stabilizer bar are connected to each other and twisted to provide different sizes of feedback according to the roll of the vehicle. torque to achieve sports roll control mode. 3) Electronic stability program (ESP): equipped with lateral acceleration sensor, deflection angular velocity sensor, longitudinal acceleration sensor, steering angle sensor, wheel speed sensor and brake pressure sensor. The steering angle sensor and wheel speed sensor are used to control the vehicle stability through the ECU to control the throttle and wheel braking. 4) Anti-lock braking system (ABS): It adopts dual-circuit four-channel independent control, which can trigger the operation of ABS during the braking control process and clearly reflect the changes in brake oil pressure during the ABS control process. (2) Draw the corresponding circuit schematic diagram on the measurement and control panel, and set up computer terminals, sensors, and actuator test holes. A general instrument meter can be used to detect the signal parameters of electrical components. It is equipped with a standard diagnostic interface, and a general or special fault diagnosis instrument can be used for detection and diagnosis. Fault. (3) The experimental bench is equipped with a fault simulation system, which has the function of setting and troubleshooting faults, and can set sensor, actuator and ECU faults. The fault setting points are comprehensive, safe and reliable, and there is no damage or damage to the four major assembly components. (4) It can realize all sensors, actuators and ECU electrical detection and some signal simulation. 5) Mechanical assembly and fitter assembly virtual simulation software: This software is developed based on unity3d, with optional 6-level image quality. It is equipped with the design and virtual disassembly and assembly of reducers and shafting structures, the design and simulation of common mechanical mechanisms, and a mechanism resource library. For a typical mechanical mechanism (virtual disassembly and assembly of a gasoline engine), the software is a whole software and cannot be individual resources. A. Reducer design and virtual disassembly interface can choose worm gear bevel gear reducer, two-stage expanded cylindrical gear reducer, bevel cylindrical gear reducer, coaxial cylindrical gear reducer, bevel gear reducer, and one-stage cylindrical gear reducer. Gear reducer. Worm bevel gear reducer: After entering the software, the assembly content is automatically played. Each step in the video has a text description . Secondary expandable cylindrical gear reducer: After entering the software, the content is played in the form of a video. The video content should include: Part name ( Scan the QR code to see the names of parts), disassembly and assembly demonstration (including disassembly and assembly), virtual disassembly (including overall, low-speed shaft, medium-speed shaft, high-speed shaft, box cover, box seat) conical cylindrical gear reducer, Coaxial cylindrical gear reducer, bevel gear reducer, first-level cylindrical gear reducer: click to enter and automatically jump to the edrawings interface. 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. B. Shaft structure design and virtual disassembly and assembly interface optional parts recognition, disassembly and assembly demonstration, and actual operation. 1. Parts recognition: three-dimensional model and part name including helical gear, non-hole end cover, coupling, coupling key, shaft, gear key, hole end cover, shaft sleeve, deep groove ball bearing, any All parts can be rotated 360° 2. Disassembly and assembly demonstration: There are 2 built-in cases. When you move the mouse to the position of a cert*n part (except the base and bearing seat), the part will automatically enlarge and the name of the part will be displayed. It is equipped with disassembly and Assembly button, the function is to automatically complete the disassembly and assembly of the shaft system structure by the software. All three-dimensional scenes can be rotated, enlarged, reduced and translated 360° in all directions. 3. Practical operation: The three-dimensional parts are neatly placed on the table. Students manually select the corresponding parts and move them to the shaft system structure. The parts can be installed only when they are placed in the correct order and in the correct position. There is a restart button to facilitate students to restart. Conduct virtual experiments. When you move the mouse to a cert*n part position (except the base and bearing seat), the part will automatically enlarge and the part name will be displayed. C. Common mechanical mechanism design and simulation, optional hinge four-bar mechanism design and analysis, I\II type crank rocker mechanism design and analysis, offset crank slider mechanism design and analysis, crank swing guide rod mechanism design and analysis, hinge Four-bar mechanism with integrated trajectory, eccentric linear-acting roller push rod cam , and centering linear-acting flat-bottomed push rod cam. 1.
