The effect of shear deformation and rotary inertia are considered in the paper.

文中考虑了剪切变形和转动惯量的影响。

Servo motor has a long overload ability, have smaller rotary inertia and big plugging around moment.

伺服电机有较长的过载能力，有较小的转动惯量和大的堵转转矩。

Notes:Weight and rotary inertia are approximate value calculated by the greatest shaft-hole dia. of Y type hole.

注：重量、转动惯量是按最大轴孔直径Y型孔计算的近似值。

It is also shown that the influence of the rotary inertia of the mass block on the shear failure is not negligible.

质量块的转动惯量对于剪切失效具有不可忽略的影响。

The result also denotes rotary inertia and the shear formation of the beam have significant effect on the high frequencies.

考虑梁的剪切变形和转动惯量时，对梁的高阶频率影响较大。
