Dynamic behaviour of an elastic separating wall in vehicle containers: Part 1
by H.F. Bauer
International Journal of Vehicle Design (IJVD), Vol. 2, No. 1, 1981

Abstract: The motion of liquids carried in semitrailer tank systems is a very frequent cause of road accidents. Even in completely filled containers with flexible separating cross-walls, the dynamics of the elastic structure and liquid interaction may result in vehicle handling difficulties. For this reason emphasis is put on cylindrical and rectangular containers, for which the basic equations are presented. In this first part of a two-part paper, a short review of liquid motions in various containers with free liquid surfaces is presented, where the natural frequencies of new tank forms are shown. In addition, the procedure whereby these natural frequencies are determined, is presented for the circular cylinder completely filled with two liquids of different densities and having a separating cross-wall which may be treated as a flexible membrane or an elastic thin plate.
