Study on Friction and Wear Properties using Thin-walled Specimens

Abstract

Until now, reducing the weight of a wide range of products, such as home appliances, transport equipment, and industrial equipment has been carried out with the aim of saving energy. There are various ways to reduce weight, such as adopting highly efficient products and changing the type and arrangement of bearings to reduce size and weight. On the other hand, there is also a method of reducing the thickness of the member to reduce the weight without changing the product itself, and new damage morphologies are also occurring. As with so-called elastohydrodynamic lubrication, many researches on differences in friction characteristics due to deformation within the contact area have been reported. Authors consider the necessity to investigate the effect of deformation of friction specimen on friction characteristics and its evaluation test method.

This paper describes the results of a preliminary experiment to investigate the friction characteristics with deformed contact area by conducting friction tests using thin-walled specimens and a standard friction and wear tester.
