Problems solved by technology

[0007] The design of the present invention adopts a set of pure mechanical drive system to replace the hydraulic-mechanical drive system of the prior art, and does not need a huge hydraulic drive source (especially an energy storage device), so it solves the problem of complex equipment structure, high manufacturing and maintenance costs , the hydraulic system is easy to leak, causing environmental pollution and other disadvantages; on the other hand, the design of the present invention can reduce the average driving force, conditionally select the appropriate servo drive motor, make the equipment manufacturing easy, and further reduce the cost

Abstract

An analog device with parallelly connected redundant inputs is composed of a frame consisting of three panels perpendicular to each other, an analog platform, at least three interface modules connected perpendicularly to said three panels, and the drivers relatively connected to said interface modules. The said interface module is a mechanical one consisting of guide track, slide table, connecting rod and driver. Its advantages are simple structure, easy control and long service life.

Description

technical field [0001] The invention relates to the field of mechanics, in particular to multi-degree-of-freedom simulators, especially six-degree-of-freedom redundant input parallel simulator technology. Background technique [0002] Multi-degree-of-freedom simulators, especially six-degree-of-freedom parallel simulators (simulation platforms), are mainly used in the manufacture of large-scale simulation equipment, such as flight simulation trainer motion systems. Stewart (Stewart) mechanism is widely used at present (referring to literature " a kind of six degrees of freedom platform " (D.Stewart.Aplatform with SixDegrees of Freedom.Proc.of the Institution of Mechanical Engineers, London, UK, 1965, 180 (15 ):371-386.)), six output degrees of freedom are obtained from six inputs. This type of platform usually has a large load-bearing mass and high acceleration, and requires a large driving force when moving at high speed; it also needs to bear a large vertical gravity when...
