摘要
本文试图通过转动惯量Ⅰ、回转半径ρ、飞轮力矩GD^2各量之间的关系,阐述如何正确理解它们的概念,进而初步探讨GD^2的本质,SI单位制的换算方法,选用GD^2应注意事项及I_(si)取代飞轮力矩的趋势。
The formula GD^2 iis often used in machine designment. It is necessary to comprehend the concept of GD^2 correctly. Through the definitions, movement of inertia Ⅰ, radius of gyration, movement of fly whccl GD^2 the authors make a clear distinction and point out the ralations between them. which things are the matters needing to pay attention to, when we use it. And here also represents so much advantages when we converse the given formula from design hand book into SI unit.
