    Straps, bands and chains

    DYNA-MESS testing systems – the solution for testing belts, straps and chains. Both standard testing machines for quality assurance of raw materials and individually developed test benches for e.g. service life tests, special event tests or remaining service life tests. With an optionally available climate chamber, your products can be tested under operating conditions.

    We are DYNA-MESS. Testing systems.

    Tests

    A wide range of tests can be performed on belts, straps and chains using DYNA-MESS testing machines. Simple tensile and compression tests, tear tests, service life tests and tests in accordance with standards, e.g. DIN EN ISO 21181 “Lightweight conveyor belts – Determination of the relaxed modulus of elasticity” (previously DIN EN 1723).

    In conjunction with a climate or temperature control chamber, all of the above tests can also be performed under defined temperature and humidity conditions. Like the rest of the test, the chamber is also controlled and parameterised using our user-friendly DYNA-TCC software.

    Bearings and bushings

    DYNA-MESS testing machines are used in the development and quality control of modern bearings and bushings for various applications.

    We are DYNA-MESS. Testing systems.

    Tests

    End-of-line inspections

    Bearings and bushings often have to undergo 100% testing. DYNA-MESS has developed the special DYNA-ElastoTest testing system for end-of-line testing. However, any other machine can also be integrated into a production line. Communication with the higher-level control system takes place via our DYNA-TCC software and can be adapted to your specific requirements.

    DYNAchew: Chewing simulation on dental implants


    DYNA-MESS has developed the DYNAchew chewing simulator for chewing simulation on dental implants.

    We are DYNA-MESS. Test Systems.

    Technical properties

    DYNAchew consists of three electrically driven linear axes to accurately simulate the chewing movement. Two are responsible for the X-Y movement and the third for the vertical movement in the Z direction.

    Validation and comparability of the test method

    By defining a standard geometry for the test specimen, it is possible to compare different abutments.

    This geometry enables not only force-locking movement in the cone but also a point load on the ring surface via peak force control.

    Data sheet

    Special software for user-friendly parameterisation

    The adaptations to our DYNA-TCC software offer a simple way of setting the path of the XY table via the phase offset. It is also visualised where the vertical Z-axis applies the highest force to the test specimen.

    Temperature control

    Peltier elements installed in the sample stage ensure the cyclical temperature change. The temperature control is parameterised via the software and then runs automatically with the test.

    This allows realistic temperatures to be simulated by cold or hot food and the implants to be tested accordingly.

    Data sheet

    Fatigue test

    Endurance tests on vehicle seats are carried out using classic vibration tests, multi-stage/block tests or cyclic ramp tests. Both the metallic seat structures and fully upholstered seats are analysed. The force is applied via back and buttock dummies in order to reproduce a load that is as close to reality as possible.

    Tensile and compressive loads

    Many test specifications stipulate alternating loads in two directions. Thanks to the servo technology used, these loads can be applied with just one test axis. The axis-integrated force and displacement measurement ensures that the desired loads and positions are approached precisely.
