Simulation Study of a Double-Acting Hydraulic Cylinder with Shock Absorber.

This paper focuses on the efficiency of the double-acting hydraulic cylinders with shock absorber at stroke end. In the present work, the simulation of two hydraulic circuits and an electro-hydraulic circuit with double-acting cylinders with shock absorber is studied. Thus, the first hydraulic circuit is made of the following components: tank, throttle check valve, 4/2-way hand lever valve with spring, filter, fixed displacement pump, and double-acting cylinder with shock absorber at stroke end (Dacs 1-1). The second hydraulic scheme has the following devices: pump unit, throttle valve, 4/3-way hand lever valve, and two double-acting cylinders with shock absorber at stroke end (Dacs 2-1 and Dacs 2-2). The third circuit studied is an electro-hydraulic scheme. The last scheme is made of the following components: tank, 4/3-way solenoid valve, nozzle, relay, valve solenoid, lamp, capacitive proximity switch, and double-acting cylinder with shock absorber (Dacs 3-1).
