6-Dof Hexapod Platform System for Aerospace Testing

Product Description

Product Description

       The six degrees of freedom motion simulation simulation platform system consists of the six degrees of freedom motion platform of the Stewart mechanism, the computer control system drive system, etc. The lower platform of the six degrees of freedom motion platform is mounted on the ground, and the upper platform is the motion platform, which is supported by six electric cylinders, and the motion platform and the electric cylinders are driven by servo motors driven by electric cylinders. The computational control system realizes the motion of the six degrees of freedom of the motion platform by coordinating and controlling the stroke of the electric cylinders. That is, three translational movements within the Cartesian coordinate system and rotation around three coordinate axes. Six degrees of freedom motion platform can be widely used in a variety of training simulators, such as flight simulators, ship simulators, helicopter takeoff and landing simulation platform, tank simulation, automobile driving simulator, train driving simulator, etc., but also can be used in motion pictures, entertainment equipment and other fields, and can even be used in the space spacecraft docking, air refueling tanker refueling docking in the processing industry can be made into six-axis linkage machine tools, dexterous robot, etc.

Machine features

The main functions of the platform are as follows:
1. Motion function; capable of yaw, pitch, roll, lift, lateral and longitudinal six degrees of freedom according to the instruction.
2. Self-locking function: it can be self-locked at any position within the motion range.
3. Safety protection function; protect the platform system under abnormal conditions, including over-travel protection, overload protection and anti-impact buffer protection.
4. Monitoring function: real-time output of the current state of each driving device of the platform. As the actuator of the driving simulation system, the all-electric six-degree-of-freedom motion system receives the dynamic attitude control data from the upper simulation control system.
After receiving the dynamic attitude control data from the upper simulation control system, the all-electric six-degree-of-freedom motion system solves the attitude control data in real time and converts it into the control data of displacement and speed of the electric cylinders in the motion platform, and drives the servo motor to drive the electric cylinder motion.
Electric cylinder movement.
In order to improve the realism of the six-degree-of-freedom platform vehicle simulator to simulate the real vehicle motion feeling, a variable input washout algorithm is proposed in combination with the classical washout algorithm. According to the simulator motion space, the input signal of the classical washout algorithm is divided and transformed according to the amplitude size, the high amplitude input signal is scaled to prevent exceeding the platform motion space; the low amplitude input signal is multiplied by a time-varying scale factor, and the determination of the time-varying scale factor adopts a fuzzy adaptive algorithm, which is based on the human body's motion sensation on the motion simulator, the human body's motion sensation on the vehicle, and the input signal. input signals, the input, output and fuzzy control rules of the fuzzy controller are selected. The simulation of vehicle longitudinal acceleration is taken as an example, and the simulation results show that the use of variable input wash-out algorithm can not only restrict the platform to the motion space of the platform, but also make full use of the motion capability of the platform, and improve the forcing straightness of the motion sensation simulation.

Features
