 Abstract

With the research conducted on viscoelastic materials and their properties; the dynamic characterisation of such materials would allow for an in-depth understanding of their viscous and elastic properties. These properties are found to be different within various polymers based on their individual shape, size and manufacturing methods used in their creation. For the research through laboratory means and the aid of RT Pro Photon 7.10 signal analyser, vibration data were obtained and analysed using MATLAB R2017b. After data processing, computational models such as Kelvin Voigt, Zener and Generalised model were used to estimate the dynamic properties of the polymer specimen. Furthermore, for validation of the results obtained, ANSYS Workbench 18.2 educational version was used to simulate the experimental methods and ensure minimal discrepancies within the linear system provided by the MATLAB model and the nonlinear simulation within ANSYS. Within this experiment, critical methods of signal analysis were used reduce noise and drift before the computation of the signal, hence improving the accuracy of the experimental results. As per the study it was found that for frequencies up to 10 Hz the parameter estimator would be a suitable fit for the set application.
