Abstract
This paper presents the expressions for the vibrational power flow (VPF) in beam-plate structures (BPSs) with isolation components for three different cases: case 1 is when the isolation component 1 (IC1) is added at the free end of the beam; case 2 is when the isolation component 2 (IC2) is embedded between the beam and the plate; case 3 is when IC1 is at the end of the beam, and IC2 is between the beam and the plate (IC1,2). The BPS is composed of a constant-cross-section beam and a thin flat rectangular plate with four edges simply supported. According to these expressions the corresponding numerical calculations are implemented. The influence of the parameters of the isolation components on the VPF is also considered. The calculated VPF in the structures are compared with the corresponding measured VPF. There is good agreement between them. The analytical method presented in the paper provides a tool for analysing vibrational energy transmission between the support roller and the armoured plate of a tracked vehicle. Some valuable conclusions have been applied to the vibration and noise control of tracked vehicles.
