Abstract:

A mathematical model was proposed to study the elastic walls oscillations of a narrow channel resting on Winkler foundation. The channel is formed by two parallel clamped plates and filled with viscous pulsating fluid. The plane problem was considered for the steady-state harmonic regime and the conversion to spring-mass system was made. The liquid pressure law in the channel and the laws of elastic channel walls oscillations are obtained.
