Durability and fatigue testing

How do vehicle components behave under extreme loads? In which areas is a component stressed and how can it be optimized? How is the material fatigued after thousands of test kilometers of a prototype fleet? Durability testing provides answers to all of these questions.

Measurement systems for durability testing

The robust imc measurement systems create the foundation for data acquisition. The modular design and universal measurement amplifier technology allow tailoring each system to the signals to be measured. Depending on the scope of the instrumentation, a number of measurement systems can be used, networked and synchronously acquire thousands of channels.

Extremely robust:
imc CRONOS-SL

  • Extremely rugged test and measurement system: IP65 protection rating. This device is ideal for testing in the harshest environments such as extreme temperatures, water spray and intense vibration
  • High precision signal conditioning for all common sensors in electro-mechanical testing
  • Autonomous PC-independent operation
  • Data storage both onboard the system and/or PC and network drive
  • High sampling rates for dynamic measurements including sonic range
  • Modern wireless transmission options available
  • imc STUDIO: configuration and operating software

    Comfortable software for acquisition, visualization and automation

    The complete operation and display of the measurement is carried out via the measurement software imc STUDIO. This allows for a comfortable configuration of the measurement - even without being connected to the system. In addition, it offers numerous visualization options for measurement data. The imc Curve Window offers extensive 1D, 2D and 3D display possibilities, as well as various interactive graphics elements.

    Simplify test stand automation

    Let control of the test environment be an integral part of your measurement application! When testing components, imc STUDIO not only measures the performance of the test object, but also allows you to integrate real-time automation and control for your test station - without programming one line of code. You simply define a state oriented test process and use drag & drop to insert ready-made functions for specifying target values, actuator profiles, control logic and even multi-variable closed-loop control systems.

    Automating routine tasks

    Save time by automating routine measurement processes using imc STUDIO. Use the drag & drop technique to create your own personal test sequence by selecting from a wide variety of functions – such as channel balancing, entering test object data, starting measurements, saving data, running analyses and printing out a report. That's it!
