Abstract: Even in completely filled road-tanker-containers with flexible separating cross-walls, the dynamics of the elastic structure and liquid interaction may result in vehicle handling difficulties. Especially since the coupled liquid-structure frequencies are drastically reduced, when compared to the uncoupled cross-wall frequencies. In this part the coupled natural frequencies of the liquid-structure are determined for a completely filled circular and rectangular road-tanker-container with a cross-wall being either a flexible membrane or an elastic thin plate. In addition some modes of excitation are also treated, for which pressure at the cross-wall and the total dynamic force of the system could be determined. Some of the results have been evaluated numerically.

Keywords: vehicle design; dynamic behaviour; elastic separating walls; excitation; free liquid surface; Lagrange equation; Laplace equation; liquid forces; liquid motion; liquid sloshing; natural frequencies; road tankers; tanks; vehicle containers.
