The testing results show that the maximum dry density of rockfill should be tested by the platform vibrator. 试验结果表明,堆石料的最大干密度需用振动台试验获得。
Industrial Computer FM-AM Hydraulic Platform Vibrator and its Optimum Design 工控机调频调幅液压振动台及其优化设计
The thesis aims to develop a micro-vibration platform using Giant Magnetostrictive Vibrator ( GMV), which is expected to improve the vibrating force and frequency scale of vibration welding technic. 针对振动焊接中激振器的激振力不大、频带不宽等缺陷,本文研制了一种以超磁致伸缩激振器为执行元件的微振动平台。
