摘要
概述了国内高频疲劳试验机的发展历程、应用原理和特点以及今后发展趋势。重点对国内目前应用的两种控制系统,即“线性扫频幅度控制系统”和“PWM脉宽调制型控制系统”的技术特点和性能进行了详细的分析和对比。
It＇s summarized the development process, basic theories, features and develop trends about China＇s domestic high frequency fatigue testing machines. It is ＂Liner scan amplitude control system and PWM pulse modulate control system＂ which is popular used in China at present. The article mostly focuses on analyzing and contrasting the technical features and performance of the above two kinds of control system.
