The six degree of freedom motion platform has the characteristics of strong load-bearing capacity, high stiffness, high accuracy, fast dynamic response, and small cumulative error. Therefore, it has been increasingly widely used in fields such as robots, motion simulators, new machine tools, and spacecraft docking devices.

A simulation dynamic cinema is built using a six degree of freedom motion platform. Through electrical selection and mechanical design, the platform is equipped with simulation software for dynamic simulation, to complete various corresponding actions at different time points of the movie screen in space.

Six degree of freedom functional characteristics:

1. Low friction loss and high transmission efficiency

Due to the rolling motion of many balls between the screw shaft and the screw nut of the ball screw, it can achieve high motion efficiency and is also very helpful in saving electricity.

2. High precision

Ball screws are generally produced continuously by high-precision mechanical equipment, especially in the factory environment of grinding, assembly, and inspection processes, where temperature and humidity are strictly controlled. Due to a sound quality management system, accuracy is fully guaranteed.

3. High speed feed and micro feed may

Ball screws utilize the motion of balls, with extremely low starting torque and no crawling phenomenon like sliding motion, ensuring precise micro feed.

4. High axial stiffness

Ball screws can be preloaded, as preloading can cause negative axial clearance, resulting in higher rigidity.

5. Reversibility with transmission capability

In order to ensure stability and prevent damage during movement, the six servo electric cylinders must achieve coordinated and consistent movements. Considering the synchronization and coordinated motion of multiple axes, the practical application environment of motion mechanisms, and the fact that the six degree of freedom motion platform is a highly coupled system, its motion control is relatively complex.

When used in a dynamic cinema, the six degree of freedom motion platform can control the real-time movement status of the seats, overlap with the movie screen, cooperate in a timely manner, simulate various thrilling and exciting movements, allowing the audience to have a more realistic experience and better immerse themselves in the movie.
