Abstract

The invention discloses an axially-moving rope transverse vibration measurement device. The axially-moving rope transverse vibration measurement device is characterized in that the device is provided with a rope circulating transmission unit, a driving wheel, a driven wheel, a tensioning wheel, a tension sensor wheel train and a first stepping motor driving the driving wheel form a circulating wheel train, a rope in a closed-ring mode is wound around the circulating wheel train to form the rope circulating transmission unit in a vertical plane; a method for measuring the fixed length, extension and shortening working conditions and the like and corresponding working conditions of the rope is achieved through separated motions or linkage of a first slide block and a second slide block; the device is provided with a displacement measurement system which is arranged right above the rope through a non-contact displacement sensor and can measure displacement of a particle on the rope right under the system in the vertical direction. The axially-moving rope transverse vibration measurement device can be used for simulating various working conditions for applying a moving rope on a project and measuring transverse displacement vibration of multiple specific points on the moving rope under various working conditions, provides an experiment basis for a moving rope model vibration response checkout computational algorithm and can be also used for moving rope vibration control.

Description

technical field [0001] The invention relates to a test device for measuring the lateral vibration of a variable-length moving rope under a given moving speed and tension. More specifically, it relates to a test experiment platform and a test system for non-contact measurement of lateral displacement vibration of a moving rope under a given initial displacement. Background technique [0002] Axial rope moving system is a type of axial moving system, which has many applications in engineering, such as cable car ropeway, tethered satellite, rope, power transmission belt, magnetic tape, paper tape, etc. The simplified mechanical models of the axial rope moving system can be roughly divided into three categories according to the changing law of the rope length. like Figure 1a Shown is a fixed-length rope moving system, which is characterized by the constant length of the study area, the rope has a moving speed, and there are new and disappearing ropes at both ends of the study ...
