: A subframe is a part of a car's structure, which uses a different frame, which varies within a larger body frame or body body to carry certain parts, such as an engine, steering train and / or suspension. The subframe is bolted and even welded to form a single assembly, attached to a car frame or cabinet structure. The main objectives of using the subframe, are to distribute the upper chassis loads over a wide area of the thin metal sheet of the body shell, and to distinguish vibrations and sharpness throughout the body. The weighted subframe design has many split benefits. As, it carries the engine load, suspension and steering parts of the car, it should be designed to be lightweight, but without interfering with power. This project proposed a robustness and modular modification of a small four-wheeled frame to be investigated. CATIA software was used to design the existing four-wheel frame. The existing small frame will be fixed with a square-shaped structure. to strengthen the rigidity and modal analysis of the new framed square structure will be performed using the ANSYS 19 software. The results and conclusions will be based on comparing the analysis and evaluation values of both subgroups.
