Resumen
Se ha desarrollado una investigación a propuesta del Ministerios de las Fuerzas Armadas como parte de
la “Tarea Triunfo”, con el objetivo de evaluar las posibilidades de fabricación de un Ómnibus Cubano
con un mínimo necesario de componentes importados, con un chasis diseñado y construido para ese fin.
Especial interés se dedica a la modelación estructural del chasis, por ser este el componente fundamental
responsable de sostener todo el peso, aportar rigidez al conjunto y condicionar la forma del ómnibus.
Múltiples invariantes han sido analizadas hasta describir su comportamiento y establecer las pautas para
su futuro diseño.
El software SAP 2000 v12 fue utilizado como soporte de la modelación, haciendo posible evaluar
diferentes condiciones de carga, analizar la influencia del sistema de amortiguación para expresar las
condiciones de apoyo, así como la posición idónea de las uniones entre perfiles para conformar los
largueros del chasis.
Se presenta además un grupo importante de conclusiones y recomendaciones para enfrentar la tarea de
diseño de dicha estructura y se dispone de un modelo calibrado que facilita sobremanera el análisis de
cualquier variable que resulte de interés.

Special interest is devoted to the structural modeling of the chassis, as this is the responsibility of supporting the weight, provide rigidity to the structure and condition of the bus how fundamental component. Multiple invari ants have been analyzed to describe their behavior and establish guidelines for future design. The SAP 2000 v12 software was used as a support for modeling, making it possible to evaluate different load conditions, analyze the influence of the damping system to express the support conditions and the ideal position of the joints between sections to form the longitudinal chassis. An important set of conclusions and recommendations is also presented to deal with the task of designing the structure and has a calibration that greatly facilitates the analysis of any variable that is relevant model.
