Apparatus for testing the rheological behaviour of elastoviscous or viscoelastic materials at variable and/or constant temperatures

摘要: The invention relates to a universal testing machine for performing compressive, tensile, relaxation, heating and cooling tests on elastoviscous or viscoelastic materials at variable and/or constant temperatures, with which the sample body lengths under temperature load changes are kept constant, can be arbitrarily varied, by means of desired/actual comparisons aid temperature-determined temperature-independent measurement apparatus stepping motor an accessory gearbox. detection very small undesired thermally loadwise effected length bodies unloaded measuring devices basis path transducers releases control pulses motor, reproduces original produces desired in dependence time.
