Design frame for car eTUL

Abstract

This paper deals with the design frame electric car eTUL. The vehicle is designed for two people sitting in a row. Presented frame construction is designed as a weldment of profiles. In its proposal was based on the proposed design of the study. Design of the frame run parallel with the verification of its properties in the finite element method and the results of this analysis were optimized. The frame was gradually analyzed at loads simulating the following conditions: static mode of the vehicle, vehicle acceleration, deceleration of the vehicle cornering, dynamic mode. The main objective was to provide sufficient stiffness at low vehicle weight. It was also determined torsional stiffness, which is an important parameter in the design of vehicle bodies.
