Abstract

El bastidor de la cosechadora cubana de caña de azúcar KTP-2M, es un elemento de un elevado grado de hiperestaticidad
y de una alta complejidad constructiva. Garantizar el diseño óptimo del mismo es un problema actual. En la presente
ponencia se expone el trabajo realizado para lograr el perfeccionamiento del bastidor de la cosechadora KTP-2M,
garantizando la resistencia y durabilidad de este con un gasto mínimo de materiales, para ello se utilizó el método
extensométrico eléctrico de medición de deformaciones y se creó un modelo físico-matemático del mismo, el cual fue
calculado mediante un sistema automatizado de análisis de estructuras basado en el cálculo matricial de estas.


Palabras claves: Bastidor, extensometría, strain gage, análisis, estructuras, durabilidad, frame.

Abstract
The frame of the cuban KTP-2M sugar cane harvester is an element of hight hyperstatic degree and hight constructive
complexity. In the following report is exposed the work done to assure the improvement of the frame in the KTP-2M
harvester, warranting its strength and durability with a minimum expense of materials. The extensometer-electrical method
of measuring distortions has been used and has been created a physical-mathematical model of the structure, which was
calculated by means of an automated system of analysis based on the Finite Elements Method.


Key words: Extensometer, strain gage, analysis, structures, durability, frame.
