Axially moving rope transverse vibration measuring system and application thereof

Abstract

The invention discloses an axially moving rope transverse vibration measuring system and the application of the axially moving rope transverse vibration measuring system. The axially moving rope transverse vibration measuring system and the application of the axially moving rope transverse vibration measuring system are characterized in that a rope is arranged on a wheel train, wherein the wheel train is sequentially provided with a tensioning wheel, a left end guide wheel, a right end guide wheel and a winding drum along the moving direction of the rope from the end where a rope winding-up device is located, and two ends of the rope are respectively connected on the rope winding-up device and the winding drum; the right end guide wheel and a synchronous motor are fixedly arranged on a moving platform of a linear motor; the moving platform of the first linear motor is arranged on a first linear guide rail in a supported mode, and the first linear guide rail is fixedly arranged on a machine frame platform along the rope moving direction; and a second linear guide rail parallel to the first liner guide rail is fixedly arranged right above the rope, a second linear motor is arranged on the second linear guide rail in a supported mode, the bottom of the second linear motor is fixedly provided with a cross beam, and displacement sensors are arranged at the bottom of the cross beam at intervals. The axially moving rope transverse vibration measuring system is used for measuring transverse vibration of the axially moving rope, can be used for testing and verifying numerical calculated results, and can also be used as a specialized course teaching platform and a scientific research experimental platform.

Description

technical field [0001] The invention relates to a test device for measuring the lateral vibration of an axially moving rope under a given moving speed and tension and its application. More specifically, it relates to a testing platform and a testing system for non-contact measurement of lateral displacement and vibration of an axially 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 model of the axial rope moving system can be roughly divided into two categories according to the change law of the rope length. a class for Figure 2a In the fixed-length rope moving system shown, the length of the research area remains unchanged, the rope has a moving speed, and there are new and disappearing ropes at both ends of...
