Diseño mediante simulación estructural en el estado estable de un elevador tipo basculante para vehículos livianos de hasta 1.4 toneladas

Abstract

In the present work the design process of a tilting type lift for vehicles up to 1.4 tons is described, mainly focused on developing a different model from the traditional ones, this equipment allows the vehicle to rotate from 0 to 90 degrees allowing a safer and more comfortable access to the underside of the vehicle. Knowing the demand and requirements of potential users allowed defining the main structural design parameters, this process that was carried out by two methods, one by means of theoretical calculations for the dimensioning of the elements and another by means of computational analysis with the use of finite elements using Hyperworks and SimSolid software. Three structural analyzes were carried out for the positions of 0 - 45 - 90 degrees, the results obtained using the Hyperworks software showed that the critical working position is when the vehicle is rotated 90 degrees, generating a Von Mises stress on the sliding axle tube of 107.5 MPa, making the most critical safety factor 2.3, considering the A36 steel construction material. On the other hand, the resistance analysis of the welded joints showed that the lowest safety factor is 1.9 for an 8mm leg size and 6011 electrode filler material. As a method of validation of results, the percentage of variation between the values obtained from the theoretical calculation and the Hyperworks software was quantified, determining a maximum error of 20% and between HyperWorks and SimSolid the difference was 15.1% percentages that are considered acceptable and allow Verify that the structural design of the equipment is correct and that its construction can be carried out following the recommendations and technical data stipulated in this document.
