Design and Development of Deployable Food Hub with Static Analysis of a Trailer Chassis using Finite Element Analysis

This paper presents the design and development of a deployable food hub with static analysis of a trailer chassis using finite element analysis. The deployable food hub includes a locally fabricated chassis and under-chassis such as leaf spring and axle, welded joints for frames that comply with AWS D1.1 Structural Welding Code-Steel, specifically NDT-MPT, a folding and expanding work area, a mechanism of being movable and deployable through the provisions of wheels, coupler and hydraulic drop-leg jacks, and multi-layered walling composed of SS304 interior and ACM exterior. A static stress analysis was conducted to trailer chassis that is made of ASTM A36 with a total load of 3354.78kg. The number of nodes and elements generated was considered, amounting to 1433916 and 4954145, respectively. Likewise, a 12-point constraint was identified at fixed locations such as leaf spring suspension and the brackets stand post connection. As a result, the minimum and maximum stress were detected at 6-point constraint, ranging from 1.4131e+007 N/m
²
to 6.93e+006 N/m
²
with a maximum displacement of 0.302mm using Von Mises stress.
