THE PARALLEL SONIC RESONATOR AS TRANSMISSION OPTIMIZATION SOLUTION FOR SONIC PROPULSION SYSTEMS

Abstract

The parallel sonic resonator as transmission optimization solution for sonic propulsion systems. Sonic propulsion systems are an alternative solution to hydraulic hybrid solutions. Based on energy transfer using waves propagated in liquids, sonic propulsion systems receive the advantages of this way to transfer energy. Low dissipation rates and due to this fact, the possibility to generate dynamical phenomena, that are associated with high energy concentrations. One of these phenomena is resonance generated in the oscillation system, liquid, trapped in a pipe. The paper presents results of analysing a sonic parallel resonance system. The parallel structure refers to the parallel connection of a sonic capacity (given volume for a given type of liquid) and impedance (oscillating mass) Parameters that influence resonance development are studied using a multidomain simulation model, in order to have an image of the possibilities of controlling resonance in order to adapt frequency to the running conditions of the vehicle.
