Parallel flexible cable suspension simulation system and parallel flexible cable suspension simulation method employing same

Abstract

The invention relates to a parallel flexible cable suspension simulation system and a parallel flexible cable suspension simulation method applying the system, which are suitable for simulation of a parallel flexible cable suspension simulation system. The device comprises driving components, movable platforms, a guide component and tension measurement components, wherein the four movable platforms are in symmetric arrangement about the center of a square; one driving component and one tension measurement component are arranged on each of the movable platforms; the driving components are connected through four flexible cables and a hanging disk; the four driving components drive the four flexible cables through a motor to further drive the hanging disk to perform movement; the four movable platforms drive the driving components to perform movement, so as to realize suspension at different positions; when the centre-of-gravity position of the hanging disk is changed, the tension measurement components transmit a signal to a self-leveling control system after monitoring that the tensions of the four flexible cables are changed, the control system controls the motor to perform motion after analyzing the signal, the action of the hanging disk is automatically leveled, the angular variation of the hanging disk is compensated, and the hanging disk can always be in a horizontal attitude. The parallel flexible cable suspension simulation system is simple in structure, can realize real-time fine regulation and suspension at different positions.

Problems solved by technology

However, in the existing parallel flexible cable suspension system, the driving devices are all fixedly placed, and the suspension simulation at different positions cannot be realized, and there are disadvantages such as poor measurement accuracy and the inability to change the center of gravity of the suspension pan automatically.
