自行火炮工作模态分析试验技术

Operational Modal Analysis Experimental Technique Used for Self-propelled Gun

利用工作模态分析试验技术完成了自行火炮全炮试验模态分析,得到了所选择自行火炮全炮模态频率分布及其模态振型,并和传统试验模态分析方法进行对比。结果表明:对相同试验对象,工作模态分析试验结果与传统试验模态分析结果一致。

The experimental modal analysis of the selected self-propelled gun was completed with operational modal analysis experimental technique; the modal frequencies distribution and modal modes were obtained; the analyzed result by the proposed method was compared with that by the traditional one. The compared result shows that obtained result by the proposed method is in agreement with that by the traditional method.
