Otimização da treliça do carro do elevador de carga industrial

Abstract

Lifts are daily equipments of people’s lives, although their application in industrial scale is very important in the internal transport of a company. With the needs of companies to cut costs to remain competitive, their products must be reliable, seeking for the lowest cost in its conception, considering it since its design until the production. Optimizing a design is undoubtedly an important role of engineering in product development. The need for lighter and stronger structure for this type of equipment is crucial to its proper functioning. With this clear idea it was held the optimization of the industrial lift truss in partnership with Euronobre Industrial Equipment’s. To obtain an optimized structure for the truss it was made use the optimization tool of the SolidWorks® ® software, along with the strain gage testing for validation of the virtual model. With the virtual model created, the optimization was performed, considering the lower and upper rectangular tubes that make up the structure, according to the profiles found in the market. Thus, new profiles were obtained with different section used in the original design, with greater thickness to reduce the effects of torsion and greater height of the section to minimize the effects of flexion.
