Abstract
This paper gives an explanation of the dynamic mechanical behaviour of a resonating microbridge mass-flow sensor. A rise in the average temperature of the bridge initially results in a reduction of the resonance frequency. Upon further temperature rise, a reversal occurs and the resonance frequency starts rising too. The dynamic behaviour in this case is found to be governed by static buckling. This phenomenon is analysed, first using a finite-element model and then with an approximate analytical calculation.
