本文通过对电液负载力、电液驱动力系统的理论分析,提出了设计电液伺服疲劳试验机的“负载力设计原则”。澄清了多年来某些文献对电液伺服力控制疲劳试验机理论分析的认识,为解决试验机系统的稳定性提供了又一种简单实用的方法。
Based on the theoretical analysis of electro-hydraulic load force and electro-hydraulic driving force system, this paper presents the design principle of load force for designing electro-hydraulic servo fatigue testing machine. Clarified the understanding of some literatures on the theoretical analysis of electro-hydraulic servo control fatigue testing machine over the years, and provided another simple and practical method to solve the stability of testing machine system.
