摘要: 针对离心机试验设备,研制了一套能在大g值离心场下工作的液压驱动系统。该系统结构上设计了船形支撑架,并在上面安装了双导轨,一边通过液压缸驱动,另一边通过辅助梁浮动连接,来保证运动顺畅;信号控制方面采用上、下位机的工作方式,两者之间采用无线路由器进行数据通讯,来解决传统设计中经集流环转接产生的信号失稳问题。将该液压系统应用于某土工离心机试验设备,在100 g离心场下完成了400 kg负载1 m行程的行走、定位等动作,满足设备功能要求。相对传统的电机或气缸驱动,该系统承载能力更强、大g值离心场下的工作可靠性更高。

Abstract: A hydraulic system working in centrifugal field of big g-force is developed for the centrifuge test. In this system, boat-shaped supporting frame is designed. To get smooth movement, double guideways are fixed on the frame, with one driven by a hydraulic cylinder, the other floating connected with an assistant beam. For signal control, host and lower computers communicating with wireless router solve the problem of signal loss in traditional connection by collecting ring. This system is applied to the test device of geotechnical centrifuge, and it meets the requirements of the device by walking and positioning in a length of 1m with a load of 400kg in centrifugal field of 100g. Compared with traditional motor or air driven mechanism, this hydraulic system has stronger load bearing capability and higher reliability working in centrifugal field of big g-force.

Key words: centrifuge, centrifugal field of big g-force, hydraulic driven, boat-shaped supporting frame, host and lower computers
