是的,当然了。 我们25年前解决了这个问题。

First of all, thank you very much for your guidance. Allow me to describe my project again. Two hydraulic cylinders, the middle is connected by a pull pressure sensor, the right is through the solenoid valve switch control hydraulic cylinder extension and recovery action, is the active end; The left side is loaded by the control force of the electro-hydraulic servo valve as the passive end; Conditions are as follows: when the right side of the hydraulic cylinder out under the control of the electromagnetic valve, the other end through the servo valve load produces a constant thrust, (5 ~ 30 kn), when back, reversing, become a pull, servo valve side is to simulate a load, put out the drive end and take action lasts 5 seconds, requirements, electromagnetic valve, after reversing internal force to stabilize 1 SEC. In the video you provided, the force can be said to be static loading, while in my case, the force applied is constant while the displacement is changed, which belongs to dynamic loading. It's keeping the force constant as the bar is coming out and coming back。thank you very much.
