Design And Simulation Of A Hydraulic Anti-shock System Based On AMESIM

In the industrial production, the shock problem often causes a huge vibration and noise. In severe it can burst tubes and make damage to the meter and seals. It is a serious threat to production safety. The shock problem often occurs when the valve or hydraulic pump opens or closes suddenly or the actuator has an emergency brake. The shock problem often happens in the chemical production. For example, in the production line of acrylic fibers in Daqing, a shock occurs in the squeezing system when suddenly changing of the valve. The shock problem makes the out of the hydraulic cylinder change and in severe can make the production stop. So it is critical to do some research to solve the shock problem.The subject of this paper is to solve the shock problem. Look at this issue from three perspectives, we can find out that there are three methods to solve the shock problem. We can use the accumulator to absorb the pressure shock. We also can use the hydraulic lock to cut off the pressure shock. The third method is to use the feedback servo control system. The design of these systems can meet requirements of the system and they can enable the system to work smoothly without pressure shock.So the main contents of this paper are three shock resistance systems'design and simulation. First, we must study the system's working principle and the structure of the three main components; Secondly, according to the theory of the shock resistance, we can design the mathematical model and do some simulation; Finally, ues the AMESim to establish the system model to simulate pressure shocks in the actual production line of acrylic fibers.
