大尺寸结构振动试验系统浅析

摘要

ABSTRACT:The work sums up and studies the methods of vibration test system for large dimension structure to solve the problems of deficiency for fixing test products and lack for single vibration table. It investigated and summarized the methods and technologies that were adopted by major reliability laboratories at home and abroad for vibration test of large dimension structure. It analyzed and compared the advantages and disadvantages of different technologies and methods and introduced cases by different methods. The paper summarizes and introduces the vibration test system for large dimension structure and describes its development prospect in future.%研究总结了大尺寸结构振动试验系统现状与振动试验方法，解决随着振动试件尺寸的增大而出现的振动试验加载安装尺寸不足和单台振动台推力不足等问题。对国内外主要可靠性试验室针对大尺寸振动试验采取的方法和技术进行了研究和总结，分析与比较不同技术和方法对于解决问题的优劣，并介绍了采用不同方法进行大尺寸结构试件振动试验案例。总结并介绍了大尺寸结构产品振动试验系统，并对未来大尺寸结构产品振动试验系统的发展进行了展望。
