The equivalent section height coefficient and the ratio of material dosage of the hollow huge-frame structures were deduced based on the equal section inertia.
根据截面惯性矩相等的原则，推导了空腹巨型框架等效截面高度系数以及材料用量比。

The inertia of the frame was reduced without reducing of rigidity, and this method has provided important reference of optimum structure design of simulation table frame.
在保证一定刚度的条件下进一步降低了框架的转动惯量，为框架结构优化设计提供了重要参考。

FA467 roving frame control system is a large inertia and nonlinear system, traditional PID and self-adaption control method can not satisfy the need of this system.
