Today, we are going to discuss the "Thrust force table and formula for hydraulic cylindersA note on the "HYDRAULIC CYLINDER". Unlike air cylinders, hydraulic cylinders have a higher pressure setting in the hydraulic circuit used and a very large thrust force.Today I have created a table that shows the thrust of the hydraulic cylinder, and I will upload the information with a few additions.
Formula for calculating the thrust of hydraulic cylinders
The thrust calculation method for hydraulic cylinders is the same as for air cylinders, though,For hydraulics, the load factor must be multiplied by the output speedIt seems to be.
Quote: From TAIYO's catalog
CylinderThe actual output should be determined by considering the resistance of the cylinder sliding parts, piping, and pressure loss of the equipment.The load factor is the ratio of the actual force applied to the cylinder to the theoretical force (theoretical cylinder force) calculated from the circuit set pressure.
Theoretical thrust is assumed to be 100%,
- For low-speed operation: 60 to 80% range
- For high-speed operation: 25-30% range The first two are the following.
Basic Formula for Hydraulic Cylinder Thrust Calculation
Therefore, the formula for calculating the thrust of a hydraulic cylinder is as follows
- Push side thrust (kN) = push side piston receiving pressure area (mm^2) x set pressure (MPa) x load factor
- Pull side thrust (kN) = pull side piston receiving pressure area (mm^2) x set pressure (MPa) x load factor
As with the air cylinder, the pressure receiving area is the same as that of the air cylinder, but the thrust is reduced because the IN side (pulling side) cannot receive pressure due to the area of the rod.
Download Hydraulic Cylinder Thrust Table
Here you can download the thrust table for hydraulic cylinders. This thrust table was created with reference to the hydraulic cylinder bore and rod diameters of "TAIYO". Cylinder diameters up to φ100 are listed, and those on the market generally have diameters up to φ250.The load factor can be adjusted in this thrust table, and should be set at the time of design.
That's it.
