Material Selection for a Custom Chassis Design

Virtual prototype simulation and analysis, based on 3D modeling software is a high-efficiency and low-cost product development model. The design and testing of the mechanical properties and material selection of a custom autonomous ground vehicle (AGV) chassis for environments with rugged terrains like forests is discussed in this paper. This research tests the capabilities of the chassis to endure subjected loads in its challenging operating environment. The 3D design is built in SolidWorks® and the static structural analysis is performed. This paper also compares other research endeavors in the realm of chassis design, focusing on factors such as maximum stress, and deflection of critical sections under diverse loading conditions. The design constraints of focus were a reduction of weight, efficient material utilization, and minimizing cross-sectional dimensions. Simulation techniques were employed to narrow the best-performing materials for our chassis. The outcomes of this study encompass a well-founded chassis design achieved through stress analysis, safety factor analysis, and chassis deflection analysis. The analysis results identify material for the custom chassis to endure shocks, torsional forces, vibrations, and other operating stresses.
