Description

Technical Field

[0001] The invention relates to the technical field of simulator motion systems, and in particular to a motion system for a full-scale simulator. Background Art

[0002] In order to meet the needs of filming, it is necessary to provide the flight environment and dynamic prompts of the entire aircraft. Traditionally, a single motion platform is used to provide dynamic simulation for flight pilots or crew members. The load is too heavy, and because the fuselage is too long, in order to meet the large-angle action without the fuselage touching the ground, the height of the platform must be greatly increased. At the same time, the structural deformation caused by the length of the fuselage cannot be ignored. The strength of the mechanical structure material and the complexity of the reinforcement design scheme have led to an exponential increase in cost and difficulty in design and manufacturing. The use of AR technology and special effects animation production technology is costly and time-consuming, and it cannot provide the most realistic immersive environment experience for all personnel involved in the shooting. Therefore, it is necessary to design a motion system for a full-scale simulator to solve the above problems. Summary of the invention

[0030] It should be noted that the platform is a six-degree-of-freedom parallel mechanism, and the platform operates under the detection and control of the control system. The control system is a hierarchical control structure, and the monitoring unit is responsible for the human-machine interface interaction, accepting user operation instructions, and sending control signals to the real-time control computer; See Figure 2 The motion parameters are transmitted to the motion computer, and the motion computer calculates the motion parameters (electric cylinder displacement) of the six electric cylinders through kinematic inverse solution.

[0031] Specifically, the six-degree-of-freedom platforms are all Stewart six-degree-of-freedom motion platforms.

[0032] It should be noted that its embedded parts are fixed in the steel-concrete foundation, and the upper platform is a load-bearing platform, which is supported by six electric cylinders and three auxiliary cylinders.

[0033] Table 1 Performance indicators of a single motion platform Table 2 Height index of a single motion platform Table 3 Motion platform load index Table 4 Three-cabin linkage performance indicators Table 5 Flight attitude indicators of full-scale simulation Specifically, PLC7 is connected to tablet computer 1, tablet computer 2 2 and tablet computer 3 3, PLC7 is connected to main control console 1 4, main control console 2 5 and main control console 3 6, tablet computer 1 1, tablet computer 2 2 and tablet computer 3 3 are connected to platform 1 8, platform 2 9 and platform 3 10 respectively.

[0034] It should be noted that PLC7 receives the mode and control instructions from the network composed of tablet computer 1, tablet computer 2, tablet computer 3, 3 and master control console 1, 4, master control console 2, 5 and master control console 3, 6, and PLC7 makes overall planning and dispatching of the actions of platform 1, 8, platform 2, 9 and platform 3, 10.
