A Hydraulic cylinder (also called a linear hydraulic motor) is a mechanical actuator that is used to give a unidirectionalforce through a unidirectional stroke. It has many applications, notably in engineering vehicles.
Hydraulic cylinders get their power from pressurized hydraulic fluid, which is typically oil. The hydraulic cylinder consists of a cylinder barrel, in which a piston connected to a piston rod moves back and forth.rod moves back and forth.
Example:
Calculate the Push and Pull of a Hydraulic Cylinder.
Bore of a Cylinder (b) = 5
Pound per Square Inch (PSI)=10
Diameter of a Rod (d) =5
Angle (degrees) = 30
Solution:
Push =sin(angle)*PSI*3.1415*b^{2/4} lbs.
= 30*10*3.1415*5*2/4
= 98.00
pull =sin(angle)*PSI*3.1415*(b^{2}-d^{2})/4 lbs.
= 30*10*3.1415*(5*2-5*2)/4
= 0.00
