Abstract
With the purpose to estimate the existing methodologies of in-use guaranteed rubber life-time test, the processing of the accelerating rubber ageing results according to State Standard GOST, ISO and Research and Production Enterprise “Progress” methodology is carried out. It is shown that the experimental results analysis provides us with the similar picture, but analytical prognostic method is more advantageous because of its flexibility. Improving of the methods of processing experimental data of rubber accelerated ageing is in the scope of interest of modern mathematical modeling, which lets using more complex functions, reflecting the properties of rubber behaviour in the whole analyzed temperature and time interval without any rejection of experimental data. Such modelinglets more precisely predict rubber behaviour in different operating conditions and carry out computations in conditions of complex temperature-and-time model of rubber products storage and exploitation.
