Description
  • S cílem získat termomechanické charakteristiky pryžového materiálu byla zpracována deformační a teplotní data získaná laboratorním měřením harmonicky zatěžovaného tlumícícho prvku s předpětím F st=6kN. Je ukázáno, že vzrůst teploty při harmonickém buzení s amplitudami F0=0,5 až 3 kN a frekvencemi 10-30 Hz je exponenciální a úměrný čtverci amplitudy zatížení. Navržený matematický model dynamické charakteristiky vzorku sestává s lineární, kvadratické a čtvrté odmocniny amplitudy deformace a lineární funkce teploty. (cs)
  • Deformation and temperature data of a vibro-damping element measured in laboratory condition at harmonic loading with constant prload F st =6kN were elaborated with the aim to build termo-mechanical characteristic of rubber-like material. It is shown that the increase of temperature during harmonic loading at various amplitudes F0=(0,75,3) kN and frequencies fe(10,30) Hz is exponential in time and proportional to the square of loading amplitude. The proposed mathematical model of dynamic characteristic of specimen gained by the regression procedure consists of linear, quadratic and fourth root function of displacement amplitude Xo and of the linear correction function of temperature.
