考虑带钢的轧机主传动系统扭振数值研究
Numerical analysis on torsional vibration of main driving system of rolling mill with strip steel
摘要
Abstract
When a strip steel is taken as a connecting link between the stands of main driving systems its dynamic characteristics influence on the torsional vibration of main driving system dynamic performance. Therefore it is necessary to study the torsional vibration model of main driving systems connected by the strip steel.By using the ANSYS software a finite element model of double stand main driving systems with connecting strip steel is established and the modal analysis is carried on.Next a variable frequency force on cross section of strip steel is applied and the amplitude frequency curves of each stand main driving system at different positions are obtained by analyzing the harmonic response.Finally by comparing the result of harmonic response analysis with that of the modal analysis the relationship of intrinsic property between strip steel and torsional vibration of main driving system is discovered.关键词
