摘要
实验模态分析技术正受到国内外工程界的极大重视,由于需要复杂昂贵的专用分析设备因而限制了该技术的推广及应用。本文探讨了用普通微机来实现模态分析。在阐述其理论的基础下,介绍了所研制的微机模态分析系统,通过试验及分析,验证了该系统的正确性及合理性,并已应用于工程实际。
The engineering circls at home and abroad are attaching great importance to the technology of experimental modal analysis. The expensive special equipment is needed while analysising, so the application is limitted. The development of microcomputer modal analysis system is studied. Based on its theoritical description the microcomputer system is presented. After a series of tests and analysis, the rationality and correctness of this system is verified and has been applied in engineering.
