Abstract

The invention provides a semi-active six-degree-of-freedom simulation device, which aims to solve the problems of high manufacturing cost and low safety due to active control over the simulation of a six-degree-of-freedom floating state of a spacecraft under the outer space weightless condition and poor simulation effects and high resistance due to the adoption of a passive control mode. An air foot is connected with a lower connecting plate through a connecting rod; the lower connecting plate is connected with an upper connecting plate through a vertical column; the two ends of a feed rod are connected with the lower connecting plate and the upper connecting plate respectively; a first end of a screw rod is connected with the lower connecting plate; a second end of the screw rod penetrates through the upper connecting plate to be driven by a motor; the screw rod is connected with a sliding block through a nut; the feed rod is connected with the sliding block through a sliding sleeve; the sliding block is connected with pitching shafts on the two sides through a force sensor; a pitching frame is arranged on the pitching shafts through a second bearing; the nut is used for fixing the bearing; and a mounting plate is arranged on the pitching frame through a first bearing. The device has the advantages of active simulation modes and passive simulation modes, and is a six-degree-of-freedom floating state simulation device which has low manufacturing cost and a good simulation effect and is safely used.

Description

technical field [0001] The invention relates to a simulation device for a semi-automatic six-degree-of-freedom aircraft, belonging to the technical field of space flight simulation. Background technique [0002] With the further development of aerospace technology, there is a need for a ground device capable of simulating the six-degree-of-freedom floating state of a space vehicle (such as a satellite) in a space weightless environment, so that the space environment can be simulated for ground simulation experiments. At present, the ground simulation equipment used mainly adopts the active control method and the passive air flotation method. While the simulation equipment completes the six-degree-of-freedom floating motion of the aircraft in space, it has the problems of high cost, poor safety and poor simulation effect due to high resistance. Contents of the invention [0003] The invention provides a semi-active six-degree-of-freedom simulation device, which is used to s...
