Electrical test axes

Test axes for furniture testing, component testing, and material testing

Electric test axes (also known as electromechanical test axes or electric axes) can be used to perform continuous load tests, fatigue strength tests, functional tests, and also static tensile tests, compression tests, bending tests, and peel tests. These test axes have a wide range of applications, including furniture testing, component testing, and material testing.

Advantages of electrical test axes

  • High control precision across the entire load range
  • High-precision position control
  • Variable stroke and load stage
  • Low noise
  • Space-saving thanks to choice of axial or radial design
  • Modular and flexible for use in individual test rigs and test fields
  • Wide range of applications: suitable for functional tests such as tip-on mechanisms or soft-close systems as well as for low-dynamic continuous load tests
  • Easy integration and variable arrangement in test fields using our motion adapters:
    • Freely positionable
    • Height/width adjustable via roller-guided clamping
    • Application-oriented setup with short setup times
  • High flexibility in the test sequence in combination with our test software
  • Allows standard-compliant tests according to DIN EN ISO, BIFMA, BS, NEN, GB, IS, etc. or individual test sequences (test templates can be freely configured)

Mechanical design and technical capabilities

Types of electrical test axes

Test axes with spindle drive

Versions

Servo motor or stepper motor possible

Application

  • Material testing (including textiles, foams, plastics, metal)
  • Furniture testing (including chairs, tables, beds, doors, drawers)
  • Component testing (including springs, hinges, fittings, casters)

Electrical linear axes

Versions

Two designs:

  • Push rod
  • Toothed belt guide

Application

  • Testing of hinged doors, sliding doors, roller doors, filing cabinets, drawers, and hinges
  • Roll tests on seating furniture, containers, and rolling tables

Rotary drives

Versions

  • Electric motor test axis for the rotary movement of the turntable, position-controlled, rotation angle +/- 360°
  • Electric motor swivel unit with swivel range +/- 180°

Application

  • Swivel chair testing
  • Door testing
  • Fittings testing

Possible control concepts

Expansion options

  • Measuring sensors that can be synchronized with the system clock and integrated into the evaluation/logging process
  • Operation of the E-axes in temperature control/climate chambers - System with integrated heating, active ventilation, and separate electronics
  • Design for special test tasks, e.g., for complex seat mechanisms or bicycle applications

Control via test software

With the help of the test software, it is possible to define movement sequences almost entirely freely. This also includes switching between different speeds during movement and reacting to events such as reaching defined positions or forces, time marks, etc. To do this, specific program blocks are processed one after the other. These can in turn be called up cyclically.

The test data can be evaluated, logged, or exported internally. In addition, test sequences and test results are securely stored and managed in the SQL database. A convenient search function allows you to quickly find and compile various tests and evaluate them statistically. This makes it easy to process statistics and complaints.

Further advantages of connecting to test software:

  • Single-axis and multi-axis tests; simple and complex test sequences – no programming knowledge required
  • Integration of external sensors as measured or controlled variables (temperature or noise level sensors, light barriers, etc.)
  • Connection to Outlook, e.g., to monitor the test sequence with an email notification if the test is interrupted
