Test Cylinders 101
What are Test Cylinders?
Test cylinders are used extensively in the testing sector and can be used for checking the functional safety of systems, component parts or products, for structural testing of airplanes, refrigeration compressors, automobile exhaust systems, or for simulating loads and movements, such as operational profiles and flight profiles.

Application Examples and Solutions
Hydraulic Test Cylinders are used in a wide variety of applications including automotive testing such as lifecycle tests, aerospace system tests such as load and environmental condition simulation, and fluid power operating condition simulation.
Automotive
Servo hydraulic lifecycle tests are the current industry standard for automobile components that are used far beyond safety-related structural elements. Users can depend on hydraulic test actuators for high positioning accuracy and reliability in applications for test systems and real time control. A test cylinder with a dynamic lift of up to 35 mm (1.3 in.), speed of 1.3 m/s (51.2 in/s), and acceleration of up to 50 m/s (1968.5 in/s) could be used for a test load requiring up to 28 kN (6,294 lbf) and a frequency up to 20 Hz.
Aerospace
System tests that simulate loads and environmental conditions in different flight phases are particularly demanding. To test the landing flaps and slats, servo hydraulic cylinders could be used here to replicate the airflow that involves rapidly changing forces with irregular parameters. For example, a servo cylinder with a bore between 40 to 160 mm (1.5 to 6.2 in.) could be used for a test stand with a holding force between 140 – 300 kN (31.4 to 67.4 lbf) and a stroke requirement of 300 to 1,670 mm (11.8 to 65.7 in.).
Fluid Power
To determine the characteristic values of a seal, seal test benches are suitable for simulating a wide range of operating conditions. Double rod cylinders could be used here for fatigue tests focused on examining the frictional force of the seals, tightness on rods and shafts.
