摘要
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。
The Bi-directional Seal Door system( BSD,Bi-directional seal door) is the key part of TECA( Transfer Equipment Cask) transfer vehicle system. Because of the non-symmetric characteristics about the single rod piston cylinder,it may cause the inconsistency for BSD during opening and closing. The paper mainly introduces the composition,function and movement process of the BSD hydraulic system. It finds the relationship between the control signal and the velocity of the cylinder through theoretical calculating. The expression shows that the load force could be used to revise the hydraulic system and to eliminate the inconsistency. The system model is built by AMEsim software. The simulation results show that the method can eliminate the influence caused by the non-symmetric characteristics for BSD system.And this method provides a reference for optimizing the BSD hydraulic servo control system.
