An In Vitro Vibration Simulation Experiment Platform for Asynchronous Rolling

Abstract

The invention discloses an asynchronous rolling external vibration simulation experiment platform which at least comprises an external vibration generation device. The external vibration generation device comprises an upper roller assembly, a lower roller assembly, a horizontal power-assisted mechanism, a vertical power-assisted mechanism, a horizontal drawer type telescopic mechanism, a verticaldrawer type telescopic mechanism, an eddy current vibrator, an eccentric assembly and a spring feedback mechanism. The eccentric assembly directly acts on the eccentric support and enables the eccentric support to vibrate axially, and indirectly acts on the eddy current vibrator fixed to the eccentric support to achieve axial vibration or superposition of axial vibration and torsional vibration, and the spring feedback mechanism and the eccentric assembly correspondingly and reversely act on the eccentric support to provide feedback energy. The asynchronous rolling external vibration simulation experiment platform is beneficial to revealing the influence of rolling vibration on the rolling forming quality of a rolled piece, clarifies the influence rule of external vibration and the rollingforming quality of the rolled piece, provides effective experiment data for the research, and provides a more accurate simulation experiment platform for rolling vibration.

Description

technical field [0001] The invention relates to the technical field of rolling vibration detection and simulation experiment drills, in particular to an asynchronous rolling external vibration simulation experiment platform. Background technique [0002] External vibration of asynchronous rolling is a major technical problem plaguing iron and steel enterprises worldwide. On the one hand, the external vibration causes the rolling force to fluctuate accordingly, and affects the rolling deformation zone. The changing rolling force eventually leads to fluctuations in the thickness of the rolled piece on the exit side, which affects the quality of the rolled piece; on the other hand, the strong external vibration will make the rolled Parts break and cause other mechanical equipment to fail at the same time. [0003] Nowadays, the forming quality of rolled pieces is the embodiment of the rolling technology level of various enterprises. The forming quality of rolled pieces directl...
