Functional Test

ACTS-SDT's Dampers are continuously monitored according to strict quality standard from design, material acquisition, manufacturing, tests to delivery.

The resulting sinusoidal damping force, velocity and displacement as a function of time should be recorded. The test results shall be plotted as wave patterns as a function of time and as a force- displacement hysteretic loop.

The force-displacement data of the first hysteretic loop shall be mathematically reduced to identify the damper's dissipative energy efficiency.
