Abstract

Purpose

The frictional behavior of glass fiber reinforced plastic (GFRP) under natural frequency of the experimental set‐up is yet to be investigated. The purpose of this paper is to investigate the frictional behavior of GFRP under natural frequency of the experimental set‐up.

Design/methodology/approach

Experimental vibration is generated artificially in such a way that direction, amplitude, and frequency of vibration can be controlled.

Findings

The presence of natural frequency of vibration indeed affects the friction force considerably. The natural frequency of vibration decreases with the increase of added dead loads to the experimental set‐up. The values of friction coefficient increase with the increase of natural frequency of vibration of the experimental set‐up. As the friction coefficient increases with increasing natural frequency of vibration, therefore maintaining appropriate level of natural frequency vibration friction may be kept to some lower value to improve mechanical processes.

Practical implications

It is expected that the applications of these results will contribute to the improvement of different concerned mechanical systems.

Originality/value

The research is carried out experimentally and it can be expected the experimental results can be used for designing mechanical machine and systems.
