摘要
针对传统振动台子结构试验的界面力施加需要反力墙作为附属加载装置、控制系统复杂等问题,研制了一种用于振动台子结构试验加载的电液伺服驱动AMD系统。在对液压伺服阀、液压动力机构和液压执行机构的性能需求进行分析的基础上,建立了电液伺服AMD系统的系统模型;设计加工了电液伺服AMD装置,并进行的AMD系统性能测试。试验结果表明该系统具有动态特性好,体积小,控制精度高、系统刚度大等特点,可以用于实时子结构试验的加载装置,又可用于结构振动控制相关领域的试验研究。
Focused on the interface force loading problem on real-time substructure shaking table test, an AMD system driven by electro-hydraulic servo actuator to avoid the use of reaction wall and sim-plify the control system was developed. Based on the performance analysis of the hydraulic servo valve, the hydraulic power mechanism and the hydraulic actuator, the system model of the AMD system was established, and the designed and performance test of the AMD system is carried out also. The tests results show that the AMD system has the characteristics of good dynamic perfor-mance, small size, high control accuracy and large system stiffness and so on. It could be used as a loading device for real-time substructure test and could also be used in the related fields such as structural control testing.
