摘要
以SKYP— 4 1 2 2 5型数控回转头压力机机身为分析对象 ,通过大型结构分析软件MARC ,采用Lanczos法对其进行了模态分析 ,求出了该压力机的前 1 0阶固有频率和振型 ,并根据分析结果对结构进行了改进 ,提高了机身的动态特性。
The first ten modes of the Straight-side frame of CNC turret press have been calculated by Lanczos method in large structure analysing software MARC with results of natural frequencies and modes which have helped to improve structure with significant improvement on frame dynamic characteristics.
