摘要
该文根据液压执行机构在运动过程中的近似力平衡,并考虑到流体粘度、运动速度与流体压力在运动过程中的关系,建立液压执行机构动作时的力平衡方程。根据该方程可以判断在不同粘度下系统是否已经达到溢流,并求解出实际进入液压缸的流量,进而求解出液压执行机构的动作时间。该计算方法经过仿真分析和大量试验验证,完全满足工程计算的需要,可以对有时间控制要求的系统在设计阶段做出准确的分析预估。
According to the approximate force balance of hydraulic actuator in the movement process, and taking into account the relation-ship among the viscosity of the fluid, motion velocity and fluid pressure in the movement process, a force balance equation of the hydraulic actuator was built. According to this equation, we can determine whether the system overflow or not in different viscosity, and get the actu-al flow into the cylinder, thus solving the hydraulic executing action time. This calculation method fully meets the need of engineering calcu-lation by simulation analysis and experiments. In the design stage the method can give accuracy analysis and estimate of the system which require time control.
