摘要

The aim of this study was to evaluate the mechanical strength of a modular car trailer with a sandwich panel floor using experimental and numerical methods. In the study, an examined trailer was subjected to finite element method (FEM) analysis to simulate the trailer’s response to various loads and boundary conditions. Then, operational testing under real-life conditions was performed, which involved loading the trailer to its total permissible laden mass (TPLM) and measuring the resulting deformations using an analog sensor after test runs, evaluating the loss of flatness as a measure of deformation. The results obtained using FEM and experimental testing showed no proof of either plastic deformation or any structural damage to the trailer floor. The study demonstrates the effectiveness of FEM and experimental testing in evaluating the mechanical strength of modular trailers. This approach enhances the reliability and efficiency of modular trailer design, contributing to increased efficiency of the design process of machines and vehicles.
