ANALYSIS OF LIGHT STEEL CANOPY FRAME STRUCTURE BASED ONSOLIDWORKS SIMULATION FOR FRAME DESIGN OPTIMIZATION

Abstract

The lightweight steel canopy frame serves as the main structural element that must be able to withstand static loads safely and efficiently. However, canopy frame design is often carried out without adequate structural analysis, potentially causing excessive deformation and the risk of structural failure. The main problem in this study is the low stiffness and safety factor in the initial canopy frame design. As a solution, geometric modifications were made to the frame to improve structural performance. This study used a SolidWorks-based Finite Element Analysis (FEA) simulation method with static loading conditions. The parameters analyzed included Von Mises stress, displacement, strain, and safety factor with a load of 700 N. The simulation results showed that the design modification was able to significantly reduce stress and displacement and increase the safety factor. Modification Model 2 produced the smallest displacement of 1.00 mm and a safety factor of 2, so it is recommended as the most optimal and safe canopy frame design for application.
