Problems solved by technology

However, at present, there is no mature method or device capable of simulating this kind of complete weightless motion in the vertical direction. Generally speaking, there is still a big gap between the effect that the device can achieve and the required complete weightless state.

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1~3 As shown, the present invention includes a sling 1, a pulley shaft 2, a driving member pulley 3, a counterweight pulley 4, a driving member 5, a counterweight 6, an air-floating guide post 7, an air-floating slider 8, a counterweight guide post 9 and The servo motor 10 has two pulley shafts 2 arranged in parallel, and the pulley shaft 2 adopts a hollow structure. Each pulley shaft 2 is equipped with a driving piece pulley 3 and two counterweight pulleys 4, the driving piece pulley 3 is arranged in the middle of the pulley shaft 2, and the two counterweight pulleys 4 are symmetrically arranged on both sides of the driving piece pulley 3, The radius R of the counterweight pulley 4 is greater than the radius r of the active member pulley 3 . The two ends of each pulley shaft 2 are respectively installed on the air bearing housings 12...

Abstract

The invention relates to a realizing manner of weightless motion state simulation, in particular to a weightless motion state simulation device comprising two pulley shafts, drive member pulleys, counterweight pulleys, a drive member, counterweights, air floating guide posts, counterweight guide posts and two servo motors. The pulley shafts are arranged parallelly, the drive member pulleys and the counterweight pulleys sleeve each pulley shaft, the counterweight pulleys are arranged on two sides of the drive member pulleys symmetrically, and two ends of each pulley shaft are respectively and rotatably connected to the upper end of one air floating guide post; the drive members are connected to the air floating guide posts through air floating sliders, and two ends of the drive members are connected to the drive member pulleys on the same sides through hanging belts; the counterweights slidably sleeve the counterweight guide posts, and two ends of the counterweights are respectively connected to the corresponding counterweight pulleys through hanging belts; the two pulley shafts are respectively connected to the servo motors arranged at two ends of the pulley shafts. The weightless motion state simulation in vertical direction is realized by the method of proportional counterweight, and dynamic characteristics of a system after being counterweighted are consistent with those of the system itself.

Description

technical field [0001] The invention relates to a realization method of weightless motion simulation, in particular to a weightless motion state simulation device. Background technique [0002] In order to simulate a complete six-degree-of-freedom environment in space, the air flotation method can be used to realize the freedom of translation and yaw rotation in two horizontal directions, and the two-dimensional turntable and reasonable counterweight structure design can realize the two rotation freedoms of pitch and roll. The freedom of translation in the vertical direction requires that a gravity-free environment can be simulated, and the active part can be in a free state at all times, so it is necessary to always provide a force equal to and opposite to gravity for balance, and as the active part moves up and down as required Within the range of motion stroke, the active part is completely free. However, at present, there is no mature method or device capable of simulat...
