Teplotní účinek na rheologické vlastnosti pryžového prvku
Půst, Ladislav ; Pešek, Luděk ; Vaněk, František ; Bula, Vítězslav
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.

History of Conferences and Colloquia on Dynamics of Machines
Půst, Ladislav
An overview on series of cnferences and Colloquia on Dynamics of Machines organized in the first place by the Institute of Thermomechanics of Academy of Sciences of Czech Republic. This overview includes scientific meetings from the first Conference held in Liblice Castle in 1958 up to the last Colloquium in 2007. the list of Conferences is the attachment to the exhibition of Proceedings organized in the frame of Colloquium "Dynamics of Machines 2007".
