Diseño de un autotanque de cabeza semiesférica, de 8000 GLS para transporte de GLP, mediante la aplicación de software CAE.

Abstract

The current graduation work aims to design a cargo tank of semi spherical head of 8000 GLS for LPG transportation, by means of the CAE software application, for this Project it was performed a study of diferent cargo tanks available at terrestrial transportation of gases where the most adequate for LPG transportation is set, as well as the parts it is made of by using the ASME, AISC and INEN norms which allowed to know the different parameters for the desing such as the material and its different physical and mechanical properties, the adequate dimensioning for not violating the norm of the Transport and Public Works Ministry, minimal thickness for the pressure of design, live loads which represent the weight of the fluid, dead loads which represent the weight of the structure, maximun pressure, maximun efforts ,kinds of welding to be aoolied in the container and the frame, which eased the design of the cargo tank. The frame, the semi spherical heads, the body, mouths, bafles of the container were drawn in SOLIDWORKS and validated in ANSYS WORKBENCH where the results of deformation, effort an safety confirmed the desing. The King pin, telescope legs, axis, suspensión system and wheels were selected from catalogues base don the requirement stated in the design. Once the design was ended, the validation and selection of additional elements of the cargo tank, the engineering of detail was performed which is a collaboration for the national industry. This project aims to provide the national industry an upgraded, validated design, and construction plans. It is recommended to carry out a study mostly focused on each one of the parts of the cargo tank and risks for rollovers.
