3 DOF dynamic car driving simulator
The 3 DOF dynamic car driving simulator equipment consists of a simulated cockpit, visual simulation driving software, data acquisition system, and a three degree of freedom platform system composed of a Stewart mechanism's three degree of freedom motion platform, computer control system, and driving system. The lower platform is installed on a fixed foundation on the ground, and the upper platform is a supporting platform. The computer control system achieves three degrees of freedom of the motion platform by coordinating and controlling the stroke of the electric cylinder. The main parts are summarized as follows: 1.1 Simulated cockpit: The cockpit is made of ABS plastic shell and molded in one go, sturdy and durable, never changing shape; The appearance is simple and elegant, fashionable and bright. The five major operating components and instrument panel are configured with simulated real parts, and the steering mechanism is constructed with a real car steering gear assembly, which automatically returns to its original position in the direction of actual car revolutions; The gear cover adopts the central channel of the Santana real car, which has a real car feel. The cockpit is composed of steering gear, throttle, clutch, foot brake, handbrake and other control components, as well as seats. 1.2 Visual simulation driving software: All visual scenes are generated in real-time 3D images by computers. 32-bit true color, 24 frames per second. Multi degree of freedom mathematical model, achieving realistic and dynamic simulation of various road and related driving skills exams and training projects for car simulation driving. 1.3 Motion Platform: A three degree of freedom motion platform performs corresponding movements based on motion control instructions; The system control server extracts corresponding actions according to the content of the 360-degree video, and solves them into motion commands that can be recognized by the motion control, while controlling the simultaneous operation of the 360-degree video of each player. 1.4 Up and down motion platform: Up platform, connecting the mechanism that needs to be simulated for action. The upper hinge is a Hooke hinge structure with double rotating shafts, used to connect the piston rod of the upper platform and the electric cylinder. Lower hinge, single hook hinge structure, used to connect the fixed base and the cylinder of the electric cylinder. Lower the platform and install the fixed base. 1.5 Computer Control System Hardware: Motion Control Computer (Servo Control Unit): Implement platform system start/stop, receive pose control information from the upper computer, perform motion control on the electric cylinder, monitor the working status of the servo motor driver, monitor the motion status of the system, complete fault handling, and safety protection work. 1.6 Signal conditioning unit: Complete the conditioning of various sensor signals, test signals, and digital I/O signals related to the motion status of the platform system, as well as the driving of servo drivers. 1.7 System control software: The software of the motion control computer includes motion control software and logic control software.
