Abstract

The current design/manufacturing field looking for value added/engineering projects. In this study, an attempt has been aimed to predict the wear of the sliding surfaces in the development stage it self which will be results in the increase of durability of the components. The wear for a polymer-polymer sliding surface contact in dry condition can be obtained by creating simulation. There are two inputs required for determining the wear volume loss over its usage time. One is the nodal pressure value at the contact area for small sliding steps which can be calculated by subjecting the geometrical model to the finite element analysis. ANSYS was used as finite element tool. Another one is the friction coefficient which can be obtained by custom designed experiments. For the calculation of friction coefficient, prototype to be subjected to unlubricated pin-on-disc experimental setup. The wear rate can be calculated by graph by plotting between pressure and cycles. Swiveling of mirror over the base resulted in the wear. By the above techniques, the wear loss and reliability of the rear mirror can be predicted.
