    Rubber/metal elements

    Elastomer components are tested both statically and dynamically. DYNA-MESS testing machines are used worldwide for both types of testing, both in development laboratories and in production for 100% testing at the end of production lines.

    We are DYNA-MESS. Test Systems.

    Tests

    Static characteristic values

    Measurement of characteristic curves and stiffnesses at different operating points

    • Hysteresis
    • Static rigidity

    Dynamic testing

    • Swing around defined preloads/displacements
    • Hysteresis
    • Dynamic stiffness
    • Loss angle
    • Damping work
    • Durability

    Static limit load test

    • Load increase until the damper fails (breakage …)

    Sweep test

    • Dependence of the dynamic spring rate on the excitation frequency
    • Dependence of the dynamic spring rate on the exciter amplitude
    • Dependence of attenuation on frequency and amplitude

    Service life tests

    • Dynamic endurance test with known excitation frequency
    • Investigation of the dynamic long-term behaviour (e.g. dynamic creep)
    • Assessment of damage patterns (fatigue, vulcanisation detachment…)

    Laboratory testing and series testing

    On the one hand, the test benches can be designed as testing machines for individual tests in research and development or for quality testing during production. On the other hand, production-integrated test stations (DYNA-ElastoTest) are also possible, which are equipped with appropriate feed systems for the test specimens (engine mounts, chassis mounts, etc.) and standardised interfaces for communication with the production line.

    DYNA-ElastoTest

    Cost-effective servopneumatics, powerful servohydraulics and flexible servoelectrics

    Depending on the test requirements (test force, frequency, stroke), the systems are designed as servo-pneumatic, servo-hydraulic or servo-electrically controlled testing machines. The more cost-effective servo-pneumatic systems can be used at frequencies of up to approx. 35 Hz. Servo-hydraulic systems are used for test specifications up to several hundred hertz test frequency. Energy-efficient, low-maintenance and low-noise servo-electric systems are used for tests up to 150 Hz.

    Material testing

    The characteristic values of materials are determined both statically and dynamically. DYNA-MESS testing machines can be used for both types of testing from a few Newtons up to the meganewton range. We are guided by global guidelines and standards as well as individual customer specifications.

    We are DYNA-MESS. Test Systems.

    Tests

    Standardised sample forms


    In contrast to component and part testing, materials are generally tested on standardised specimens. A classic example of this are tensile tests on metallic specimens in accordance with EN 6892.


    In quasi-static tests – often referred to as “static tests” – the load is applied so slowly that dynamic effects do not play a role. Typical results of quasi-static tests are, for example

    Quasi-static tests

    • Tensile strength Rm
    • Yield strength ReH/ReL
    • E-modulus E
    • Elongation at break A
    • Spring stiffness C
    • …

    Dynamic tests

    In dynamic tests, a – usually cyclical – load is applied with a corresponding test frequency. These can be threshold load tests in the tensile or compression range as well as alternating load tests with tensile and compression components.

    Dynamic tests are used to determine characteristic values on the one hand and to test service life on the other. Typical dynamic characteristic values are e.g.

    • Wöhler curve
    • Service life
    • Hysteresis curve
    • Dynamic stiffness Cdyn
    • Loss angle φ
    • Loss work Wverl
    • …

    Individual testing and endurance testing


    While the static and dynamic characteristic values of the materials are determined in individual tests, the long-term behaviour under dynamic load is examined as part of endurance tests. The continuous data recording of the DYNA-MESS testing software documents both the running-in effects at the start of the test and the change in the test specimen during the test period.

    Matching accessories

    In order to fulfil the requirements of the various standards, we offer additional accessories such as clamping fixtures, special and standard-compliant devices, tactile or non-contact extensometers in longitudinal and transverse direction, temperature control devices …

    Vertical testing machines
    Table top testing machines

    Application example: Screws up to M 72

    Fasteners used in wind power technology, for example, place high demands on testing technology. Bolts with a size of up to M 72 can be loaded with forces in the meganewton range and pulled until they break. The testing software ensures that a tensile test is carried out in accordance with EN 6892, in which all parameters such as modulus of elasticity, tensile strength, yield strength, etc. are determined.

    The machine frames are designed as a 2- or 4-column construction and are characterised by maximum machine rigidity. They are therefore ideally suited for static and, in particular, dynamic tests.

    Drive types

    The most suitable drive types are used depending on the individual testing requirements of our customers. In addition to the desired nominal force and the required dynamics, aspects such as component behaviour and ambient conditions also determine the selection of the right drive.

    With servo-pneumatic, servo-electric or servo-hydraulic drive concepts, we cover a wide range of requirements. The nominal forces range from 10 kN to several meganewtons.

    In addition to the machines for purely static testing, variants for low cycle fatigue tests (LCF) for test frequencies up to 10 Hz and for high cycle fatigue tests (HCF) for test frequencies up to 100 Hz are available.
