Spring Testing Machines

The spring testing machines of WPM are used for tests of screw springs, leaf springs, rubber springs and spring assemblies.

The following tests can be carried out:

Spring Testing Machine FED D 250C1

Application

  • To test leaf springs, screw springs and rubber springs as well as spring assemblies

Features

  • Automatic test run
  • Nominal force: 250 kN
  • Measurement unit for transverse forces and eccentricity of the force centre

Spring Testing Machine FED B 400 C

Application

The spring testing machine is designed to test rubber spring washers, screw springs and leaf springs for railway vehicles.

Features

  • Thanks to the electronic force and displacement control system, individual control of force and displacement is possible, including force holding and linear force increase or decrease and displacement increase or decrease in predefined velocities.
  • The C-shape machine frame guarantees high stiffness.
  • The whole area of the machine table is secured by means of a safety enclosure. This enclosure prevents from reaching into the specimen area and protects the operating personnel against flying parts. It is not possible to open the safety enclosure during the test.
  • Axial test force: 400 kN
  • Automatic test run
  • Auccuracy class 0.5

Triaxial Spring Testing Machine FED D 400

Features

  • Spring testing machines for test forces up to 400 kN (600 kN possible) of accuracy class 0.5
  • Spring load in direction of longitudinal axis of the spring and in all cross directions
  • Equipped with force and displacement sensors together with freely programmable digital control
  • Automatic programmed tests and evaluation
  • Basic version for screw springs with a weight of 200 kg, a free spring height of 1200 mm and an outer diameter of 650 mm
  • Ends of the spring can be moved laterally under load to up to 200 mm in every direction
  • Lateral forces up to 150 kN
  • Key values can be customized
  • Full support of EN 13298:2003 (standard for tests of screw springs for track vehicles)
