THE PARAMETER DESIGN AND THE MECHANICAL MODEL OF PIANOWIRE PROBABILITY SCREEN

摘要

Based on the analysis of the piano wire’s vibration characteristics, the authors estab lished the mechanical model of piano wire proba bility screen , obtained the analytic so lution of thestable forced vibration of screen wires , and developed the para meter designfor m ula of the piano wire screen . The para meter design form ula has been used in coalpreparation industry .
