Damper Test

Introduction Damper test equipment is used to test one or

multiple damping force proportional to the speed of shaft movement. This is a machine that compresses and extends a damper at known speeds and measure the forces produced by the damper. The form of a damp test machine constructed a frame holding an electric motor with a drive reducing gear that spins a crank attached to the damper shaft through a linear bearing. Bolt holes in the crank allow several different stroke lengths.

On the top, there is placed a load cell, which measures the damper force and movement is measured using a displacement sensor. This machine is tested for several spin velocities, from rated to 200rpm. The possible stroke setting is 0 to 25mm.

After an initial user-defined compression, software calculates hundreds of instantaneous spring rates during a controlled release of the spring through the test and preload ranges. The instrument has an RS232 interface, optional memory card reader or USB to store the results on a computer. The overload protecting function can make the machine safe. It can hold the peak value. The load display can be translated among Newton(N), Kilogram(Kg) and Pound(Lb). Force

sensors are available to provide high levels of precision for damper with low force levels. Supplied with a fixed clamp to keep the plates parallel during the tests. Available as options for tensile testing, in 4 capacities: , 100N, 200 N, 500 N, 1000 N. Data acquisition was made with a The force vs. shaft speed graphs you see in this article come from data generated by testing a damper in what is generally known as a damper dynamometer.
