| 中文摘要: |
| 模态质量和模态刚度参数可通过结构固有频率相互导出，在结构动力学设计中占据重要的地位。本文对模态质量获取方法进行了研究，重点在于试验测试方法，并应用于实际梁结构，表明基于频率变化率的试验方法得到的结果误差可控制在20%左右，能够满足实际工程的需要。 |
| 英文摘要: |
| Modal mass and modal stiffness are very important on structural dynamics. They can be transformed by each other using modal frequency. This paper introduces the study on modal mass computation, focusing experiment method. The application on beam structure shows that the error of experiment method based on frequency change ratio is less than 20%, that can meet the engineering need. |
