Abstract

A procedure for the construction and assembly of a tubular chassis was proposed taking as a reference a chassis of a single seat go kart vehicle, using anaerobic adhesive joints as an assembly alternative. The methodology consisted of establishing five stages ranging from joint design to assembly. Step one of definition lies in studying the structural behavior of the chassis subjected to static loads by finite element analysis, to know the stresses to which each node is subjected, identifying and characterizing the points of the chassis where adhesive will be used. Stages two and three of measurement and design propose the optimal design of the single-match cylindrical adhesive joint. Taking into account in its design the geometric parameters of the joint and properties of the joint material (duralumin). In the cutting and bending stage all chassis elements are built, a welding matrix is designed to ensure that the chassis complies with the CIK/FIA standard and mechanical requests. Assembly starts with the dots with adhesive and then the welded ones, the adhesive joints are cured at a temperature between 80oC and 100oCfor 1 hour. The results of this work showed that bending and torsion are the critical stresses that these chassis must withstand, in addition, the assembly of the welded points should keep the joints covered in order to avoid an increased temperature that causes faults in the adhesive bond.
