ABSTRACT
This study aims to design and analyze the structural strength of a weighbridge
using the finite element method. A weighbridge is a device composed of various
components arranged to measure the weight of vehicles, ranging from light
vehicles to heavy vehicles, either unloaded or loaded. The weighbridge consists of
several main components, one of which is the frame. The frame uses WF 600 and
WF 200 steel profiles made of SS400 material. The structural strength of the
weighbridge frame is crucial to ensure its safety under loading conditions.
Therefore, a detailed design of the frame is required to prevent failure by
considering alternative materials such as ST52-3, S235JR, and S275JR. One of
the most common methods for analyzing frame structures is the finite element
method. This analysis involves mathematical calculations and simulations of the
frame structure using Autodesk Inventor. The mathematical calculations showed
the highest principal stress on bar 4 at 5.92 MPa, while the simulation yielded
5.62 MPa, with a percentage error of 4.56%. The smallest displacement value for
the S235JR material on bar 4 was 1.121 mm. For the safety factor, the highest
value was achieved using the ST52-3 material at 59.96. Based on the obtained
data, it can be concluded that the frame has a safety factor value of ≥ 4, both from
mathematical calculations and simulation results. Therefore, the frame can be
considered safe when subjected to loading from a Colt Diesel FE 74 Long 2024
truck.
