摘要
本文介绍了一种自动计算振动结构的转动惯量的方法。首先，在ＡＵＴＯＣＡＤ系统中对研究的振动结构进行几何造型，得到结构的ＤＸＦ图形交换文件。然后，用ＴＢ程序从ＤＸＦ文件中读取有关数据，计算出振动结构的重心、重量和转动惯量。本方法在工程实际中有应用价值。
A method for calculating the rotating inertia of vibration structure was recommendation. First, the DXF drafting exchange file of the structure by its geometrical model in AUTOCAD. Then, the center of gravity, mass and the rotating inertia were calculated from the data in the DXF file. The method has the value in engineering.
