Damper test stand

Damper test stand

The test bench allows for testing of various types of hydraulic dampers used in rail vehicles.
A characteristic curve is obtained that shows the dependency between the damping force on the shock absorber stroke.


FEATURES
  • Load force acting axially on the tested damper,
  • Ensures required forces and speeds of the damper,
  • Stroke speed adjustment,
  • Adjustment of the damper to a position corresponding with rail vehicle operating conditions by means of an angular pivoting mechanism,
  • Electronic control of the testing process,
  • Test is fully automated,
  • Measurement data are recorded, archived and can be printed out,
  • Temperature compensation (operating environment simulation).

TEST BENCH COMPONENTS
  • Rigid mechanical structure,
  • Mounting clamps that do not require damper rubber components to be dismantled,
  • Servomotor drives responsible for pivoting and test of a damper
  • Electrical cabinet built into the device structure,
  • PLC controller, computer with database.

Technical data
