摘要

多点激励振动试验由于能更加真实地模拟实际振动环境而被越来越多的人所重视，成为振动环境试验发展的趋势。阐述了多点激励振动试验系统基本控制原理，并对时域波形复现的关键技术迭代算法和驱动信号重叠连接，与频谱再现的关键技术反馈修正算法和时域随机化技术进行了介绍。最后对多点激励振动试验控制技术进行总结与展望。

Abstract

More and more people have attached greater importance to the multi-exciter vibration testing system since it can be able to simulate the vibration environment more real, and now it has become a development tendency of environmental vibration test. The basic control principle of multi-exciter vibration testing system，and key technologies of time-domain waveform replication , which includes iterative algorithm and overlap connective of driving signal, and frequency spectrum replication, which includes feedback correcting algorithm and time randomization are introduced in this paper. At last, this paper gives a summary and prospect of control technology for multi-exciter vibration testing.
