For the dynamic load of these tanks only few theoretical and no experimental examinations are known to this day. In the present work a contribution to the calculation of horizontal, saddle supported cylindrical shells under vertical dynamic load is performed. In this connection, special attention is directed upon the simple manipulation for practical purposes. For the numeric calculation a model is generated on basis of the finite-element-method (FEM) with 4-node shell elements after the discreet Kirchhoff'schen theory for the simulation of the vertical oscillation of lying liquid tanks. The contact between saddle and cylindrical shell is simulated by framework beams to which for pressure a linear-elastic material behavior is assigned, while with strains the Young's-module is set to zero. Through here the local take off of the cylindrical shell of the saddle can be simulated. An additional simplification of the model is the calculation of the liquid pressure from the toe acceleration of the oscillating tank. To confirm the FEM model experimental examinations of horizontal, saddle supported cylindrical shells are executed in the present work for the first time. To measure the pressure between saddle and cylinder shells the Tekscan measurement system is used. Although the measuring system is used in different areas at research and production, no systematic examination of the measuring system is known to this day. Therefore, the functional principle of the measurement system is described in detail and the mistake influences and measuring accuracies are analyzed systematically for the first time in the present work. In this connection, the measuring accuracy is examined for different calibration loads and areas, different surface materials, temperature changes, dynamic load of different frequency, shear effects of folios and the temporal drift and indicated quantitatively. For the experimental examinations of horizontal, saddle supported cylindrical shells a experimental plant is developed in the present work, so the vertical dynamic oscillation of the vessel is possible. In the main attempts of this work the filling degree, the saddle position, the saddle angle, the elasticity of an interposition between saddle and cylinder shell and the exciter frequency are varied. The displacement and strain condition of the vessel was measured at 60 measuring points, the support pressure distribution was measured with the Tekscan measurement system. With the FEM model the experimental results are checked and extended, as well as other shell and saddle parameters, as for example the shell length, the shell radius, the shell thickness etc. are examine. To represent the dependence of the numeric results of the different shell and saddle parameters, only one parameter is varied in every calculation series and the others are held. The numeric results are standardized on the parameter shell radius. A dynamic factor is developed in the present work which can be determined as a product from three partials dynamic factors diagrammatically. With the present work a systematic experimental and numeric examination of the horizontal, saddle supported cylindrical shell under vertical dynamic load is presented for the first time and also the used Tekscan measurement system was examined for the first time systematically for its mistake influences and measuring accuracies. The dynamic factor developed in the present work supply for the first time calculation indications for practical purposes which allow a fast, reasonable calculation of horizontal, saddle supported cylindrical shells under vertical dynamic load.","abstract_html":"The static behavior of horizontal, saddle supported cylindrical shells is the subject of numerous research works since long time.
