双向密封门系统(BSD,Bi-directional sealdoor)是TECA(Transfer Equipment Cask)转运车关键部件。由于驱动门运动的单杆活塞缸的非对称性使得双向密封门系统开合过程中的运动速度会产生不一致性。介绍了双密封门液压系统的组成、功能与运动过程,并通过理论计算,找出双向密封门阀控液压缸的速度与信号之间的数学关系,从数学关系中可以看出,通过负载力反馈可以对系统的非对称性进行补偿,消除运动速度的不一致性,通过AMEsim建立液压单杆模型,实验表明,此方法在一定程度上可以消除单杆活塞缸的不对称性对系统性能的影响,为双向密封门液压系统速度控制提供优化参考。
Bi-directional seal door system (BSD, Bi-directional sealdoor) is a key component of the transfer equipment truck (TECA). Due to the asymmetry of the single-rod piston cylinder driving the door, the speed of the two-way sealed door system will not be consistent during the opening and closing process. The composition, function and movement of hydraulic system of double-seal door are introduced. The mathematical relationship between the speed and signal of two-way sealed valve-controlled cylinder is found by theoretical calculation. It can be seen from the mathematical relationship that feedback through load force The asymmetry of the system can be compensated to eliminate the inconsistency of the movement speed. The hydraulic single-rod model is established by AMEsim. The experiment shows that this method can eliminate the influence of the asymmetry of the single-rod piston cylinder on the system performance to a certain extent, For two-way sealing door hydraulic system speed control to provide an optimal reference.
