that converts hydraulic energy into linear force and motion. It is a key component in many hydraulic systems used in various industries, such as construction, manufacturing, and transportation. The objective of current research is to investigate the structural characteristics of hydraulic cylinder using techniques of FEA. The modeling of hydraulic cylinder is conducted in design modeler and structural analysis is conducted using ANSYS simulation package. The FEA analysis results have shown that critical regions are obtained at the end support regions. The mid center region of the hydraulic cylinder is almost uniform. The equivalent stress at this region is nearly 96.3MPa. The hydraulic cylinder has safety factor of 1.08 which makes it feasible for the required application.
Composite cylinders with steel liners were the subject of a technique for designing strength and buckling proposed by Mantovani et al. [6,7]. An actuator with a working pressure of 35 MPa, an internal diameter of 300 mm, and a stroke of 1960 mm was used in the authors' study. The authors achieved this by adapting a solution to the Lame issue for anisotropic materials. The cylinder's initial strength, together with its circumferential and axial deformation, have been constrained in the design to provide optimal performance. Piston and front cap were made from composite material reinforced with carbon fibre, and FEM analysis was done by Ritchie et al. [8]. The pieces were fabricated from prefabricated pipes using subtractive manufacturing techniques, which are not ideal for use with composites. The composite was deemed to have middling machinability, with poor surface quality and dimensional accuracy being the results. In both corrosion tests and a comparison of their respective weights, the composite material was clearly the victor.
Key Words - FEA, Hydraulic cylinder, Safety factor 1. INTRODUCTION: Actuators like hydraulic cylinders transform the potential energy of pressurised fluid into the mechanical energy of a rotary motion. An actuator's moving element (piston or plunger) experiences a force that is proportional to the fluid's pressure and the element's area. Figure 1 depicts a double-rod hydraulic cylinder.
In order to improve tribological conditions at the barrelpiston contact, Scholz and Kroll [9] investigated removing the steel liner from the interior of the barrel of a hydraulic cylinder and replacing it with a nanocomposite coating. The authors described techniques for nanocomposite coating production and stress calculation inside individual composite layers. To combat this, Kumar and Lee [10] created hybrid piston rods that are made of steel at their core and a composite shell for added strength. Both finite element and experimental testing were conducted on a variety of components ranging in size from 7.5 mm to 30 mm in diameter and 650 mm in length. Depending on the kind of construction, the CFRP percentage might be anywhere from 0% (for solid steel rods) to 100% (for all-composite designs). There is evidence that increasing the element's composite content improves its buckling resistance.
Figure 1: Double tie-rod hydraulic cylinder [1] Front cap (1), piston rod (2), front cap (3), piston (4), barrel (5), rear cap (6), and tail joint (7) make up the parts [2]. Working pressures of up to 25 MPa are typical for standard hydraulic cylinders, with higher-pressure variants available on special order. Both the diameter and the pitch may range from a few millimetres [3,4] to several meters [5].
