Three degrees of freedom motion platform: System principle overall design this diagram is the system flowchart of the simulator. The main control module of the simulator is located at the top level of the app system, managing the real-time graphic generation system, training and assessment system, and driving simulation expert system. The data acquisition and execution system is the human-machine input interface and execution output interface of the simulator, and the overall control module of the simulator needs to manage and coordinate the data acquisition and system.
Application scope of three degrees of freedom platform
First, the dynamic platform for simulation
The payload range of the simulation dynamic platform is 0.25-20 tons. These simulation dynamic platforms control the motion of the platform by receiving status signals from the upper controller, and are widely used in various training simulator fields such as flight control simulators, ship control simulators, helicopter control simulators, tank control simulators, car driving simulators, train driving simulators, earthquake simulators, dynamic cinemas, entertainment equipment, etc.
Secondly, closely locate and test the application platform
The three degree of freedom platform is used for precise positioning testing with a payload range of 0.5t-50t and a positioning accuracy of 0.02mm. It is widely used in various automotive attitude testing equipment, aircraft/missile flight attitude testing equipment, space spacecraft docking, and aerial refueling docking. At the same time, the three degree of freedom precision positioning mechanism can be used to manufacture high stiffness and precision three degree of freedom machining machines and assembly robots (such as three-axis parallel machine tools and parallel robots), which are widely used in various complex special processing and complex assembly (such as aircraft assembly and satellite assembly).

The design principle and application of a three-degree-of-freedom motion platform. It can do any single-degree-of-freedom motion among the three degrees of freedom in space, and it can also do the composite motion of any multiple degrees of freedom. Due to the use of full digital control of the servo system and servo electric cylinder as the platform motion part of the actuator, the motion trajectory and speed of the three-degree-of-freedom simulation platform is smooth and continuous, and it can achieve both high-frequency fast motion and low-speed smooth motion.
The three-degree-of-freedom platform consists of three servo-electric cylinders, three universal comparative chains (hooker comparative chains) above and below, and two platforms above and below. The lower platform is fixed on the infrastructure, with the help of the three servo-electric cylinders' expansion and contraction movement, the platform can carry out three degrees of freedom (x, y, z, α, β, v) movement in space, so as to simulate a variety of space movement attitude.
