摘要
本文探讨合理振型数的确定及扭转振型判定 ,提出了特征参数法控制振型数 ,并与有效质量进行比较 ;定义了新的振型方向因子来判定扭转振型。
In this paper the decision of reasonable mode number and judgment of torsion mode are discussed.A method of deciding mode number by controlling character parameter is presented,which is compared with the effective mass method.A new mode direction factor to judge the torsion mode is defined in the paper.
