摘要
通过振动台系统组成部分(振动台体、磁场电源和功率放大器)涉及的结构与技术的分析,对振动台系统技术指标的先进性、结构设计的合理性及振动台用于振动试验的准确性和安全性的评价提供依据,可供选择振动台系统参考。
This paper describes the advanced technologic level, the reasonableness of the structural design, the safe and the accuracy of the vibration test in the components (the vibrator body, the magnetic power supply and the power amplifier) of the vibrator system by analyzing the structure and the technology. There are evaluable bases and references for the vibrator managers from this paper.
