通过对快速液压机动梁的运动分析,以及液压系统流体瞬变模型的研究,提出了一种根据修正正弦动梁位移曲线,并按照二维流体瞬变耦合方程,用有限元法确定主控阀启闭特性的方法,可以减少快速液压机的液压冲击与机械振动.
Based on the analysis of the motion of fast hydraulic maneuvering beam and the research on the fluid transient model of hydraulic system, a new method based on the modified sinusoidal moving beam displacement curve and the two-dimensional fluid transient coupling equation are used to determine the main control valve Opening and closing characteristics of the method can reduce the rapid hydraulic machine hydraulic shock and mechanical vibration.
