Multi-dimensional parallel dynamic platform for flight simulator

Abstract

The invention discloses a multi-dimensional parallel dynamic platform for a flight simulator. The flight simulator is composed of a PC, a visual system, a dynamic platform and a cabin. The dynamic platform comprises a planar motion platform and a six-freedom-degree motion platform. The planar motion platform is used for simulatinga translation motion sensing of a planar line or a curve and enables the six-freedom-degree motion platform arranged on the planar motion platform to simulate translation motion sensing of a planar line or a curve. The six-freedom-degree motion platform is used for simulating six-freedom-degree motion sensing and enables the cabin arranged on the six-freedom-degree motion platform to simulate the six-freedom-degree motion sensing. The cabin is arranged on the top of the motion platform. According to the invention, lamination of various motion ways can be realized perfectly and a multi-dimensional flight motion simulation effect also can be realized; and simulation flight experience of a user can be enhanced substantially. The provided multi-dimensional parallel dynamic platform can be applied to the flight simulator field widely.

Description

technical field [0001] The invention relates to the field of flight simulators, in particular to a multi-dimensional parallel dynamic platform for flight simulators. Background technique [0002] The flight simulator CNFS (CNTECHFlight Simulator) is a machine used to simulate the flight of an aircraft in a broad sense. Devices that simulate the flight of airplanes, missiles, satellites, spacecraft, etc. can be called flight simulators. It is a simulation device that can reproduce the aircraft and the air environment and can be operated. A flight simulator generally includes a simulated cockpit, a motion system, and a visual system. The motion system is used to simulate changes in the attitude and speed of the aircraft so that the pilot's body can feel the motion of the aircraft. [0003] The current flight simulator dynamic platform on the market has six degrees of freedom, that is, rotation around three axes in three-dimensional coordinates and linear displacement along t...

Problems solved by technology

It can perform six actions: left and right rollover, front and rear rollover, forward and backward translation, left and right translation, up and down lifting, and left and right rotation. The individual effects of each action are good, and the smoothness of operation is also very good. Kinematics laws; however, there are also obvious shortcomings. It cannot perform multiple actions at the same time. When an actual object moves, multiple effects often occur concurrently. The action of lifting or lowering the nose of the aircraft while moving in translation; during impact, there will be translation or rollover according to the strength of the impact, and the rotation of the aircraft will follow; for example, when the aircraft falls, it will generally be accompanied by the acceleration of gravity There will be rotation or rollover while moving down; therefore, when the current flight simulator dynamic platform simulates some extreme motion laws of natural objects, there are requirements that do not meet the actual situation, and it is difficult to simulate a relatively complete Tracks and Actions
