补充资料:转动惯量
转动惯量 moment of inertia 刚体绕轴转动惯性的度量。其数值为I=Δmiri2或I=,式中ri为组成刚体的质量微元Δmi(或dm)到转轴的垂直距离;求和号(或积分号)遍及整个刚体。转动惯量只决定于刚体的形状、质量分布和转轴的位置,而同刚体绕轴的转动状态(如角速度的大小)无关。规则形状的均质刚体,其转动惯量可直接计得。不规则刚体或非均质刚体的转动惯量,一般用实验法测定。转动惯量应用于刚体各种运动的动力学计算中。 描述刚体绕互相平行诸转轴的转动惯量之间的关系,有如下的平行轴定理:刚体对一轴的转动惯量,等于该刚体对同此轴平行并通过质心之轴的转动惯量加上该刚体的质量同两轴间距离平方的乘积。由于和式的第二项恒大于零,因此刚体绕过质量中心之轴的转动惯量是绕该束平行轴诸转动惯量中的最小者。 刚体对一轴的转动惯量,可折算成质量等于刚体质量的单个质点对该轴所形成的转动惯量。由此折算所得的质点到转轴的距离 ,称为刚体绕该轴的回转半径κ,其公式为,式中M为刚体质量;I为转动惯量。 转动惯量的量纲为L2M,在SI单位制中,它的单位是kg·m2。 刚体绕某一点转动的惯性由更普遍的惯量张量描述。惯量张量是二阶对称张量,它完整地刻画出刚体绕通过该点任一轴的转动惯量的大小。 |
