Vibration of sensor diaphragm with residual stress coupled with liquids: effect of the residual stress

Abstract

Purpose

The natural frequency of a diaphragm with residual stress in contact with a liquid is investigated theoretically in this paper. The paper aims to discuss these issues.

Design/methodology/approach

An analytical calculation using the nondimensional added virtual mass incremental (NAVMI) factors is performed to find the dependency of the natural frequency on the residual stress when the diaphragm vibrating in contact with a liquid.

Findings

The analysis gives the residual stress contribution to the added virtual mass.

Originality/value

The magnitude of the added virtual mass depends on the residual stress. However, the magnitude of the natural frequency is found to be insignificant to the residual stress.
