摘要
为了研究采煤机截割部传动系统的固有频率,建立了采煤机截割部传动系统的扭振模型,并且利用matlab计算出整个传动系统的扭振固有频率,计算结果表明,采煤机截割部工作在安全频率范围内,为采煤机截割部安全工作提供了理论指导。
In order to study the inherent frequency of the transmission system of shearer cutting part ,torsional vibration model of the shearer cutting part transmission system was established in this paper ,the author has calculated the inherent frequency of torsional vibration by matlab .The results show that shearer cutting part work in safety frequency range .This paper provides the theoretical guidance for shearer cutting part working safely .
