Six-degree-of-freedom motion platform system based on reverse gravity balance

Abstract

The invention discloses a reverse gravitational equilibrium-based six-degree-of-freedom motion platform system, which comprises a control cabinet and a motion execution mechanism, and is characterized in that the control cabinet controls the motion execution mechanism to act to realize the motion of a reverse gravitational equilibrium six-degree-of-freedom platform; the motion executing mechanism comprises an upper platform plate, a lower platform bottom plate, an electric cylinder mechanism, a hydraulic supporting rod mechanism, an energy accumulator and a hydraulic filling device, and the upper platform plate and the lower platform bottom plate are arranged at the two ends of the electric cylinder mechanism and the two ends of the hydraulic supporting rod mechanism respectively and connected with the electric cylinder mechanism and the hydraulic supporting rod mechanism through hinges; when the reverse gravity balance six-degree-of-freedom motion platform system is used, the hydraulic supporting rods are connected in parallel in the middle of the electric cylinders and move along with the six sets of electric cylinders, reverse gravity balance supporting is formed, the effect of balancing part of gravity is achieved, and the reverse gravity balance six-degree-of-freedom motion platform system can achieve better motion characteristics under the condition that the motor power is the same. The safety of the six-degree-of-freedom motion platform is greatly improved, and the six-degree-of-freedom motion platform has the characteristics of novel structure, good safety and convenience in use.

Description

technical field [0001] The invention relates to the technical field of automation equipment, in particular to a six-degree-of-freedom motion platform system based on reverse gravity balance. Background technique [0002] Usually, the motion simulation equipment of the driving training simulator adopts three degrees of freedom of pitch rotation, roll rotation, and vertical movement or six degrees of freedom of movement along the X, Y, and Z axes and rotation around the X, Y, and Z axes. The motion platform system simulates the posture of the vehicle during driving; the cockpit is connected with the upper plate of the motion platform system, and moves together with the upper plate of the platform to realize the trainee's exercise experience in the process of driving the vehicle; [0003] The existing six-degree-of-freedom motion platform refers to a parallel mechanism that completes any position and attitude in space by moving along the X, Y, and Z axes and rotating around the...

Problems solved by technology

[0003] The existing six-degree-of-freedom motion platform refers to a parallel mechanism that completes any position and attitude in space by moving along the X, Y, and Z axes and rotating around the X, Y, and Z axes. The control part is composed; the total power of the six-degree-of-freedom motion platform system is determined by the load and motion speed. For applications with large loads, high-speed motion, and power limitations, the use of the existing motion platform system is insufficient;
