Investigating The Failure of Leaf Springs in Automobile Suspension on Ghana Road

This study investigates the failure of leaf springs used in suspension system heavy-duty vehicles Ghana. Primary and secondary data were collected using both open closed-ended questionnaires. Welders fabricators Sarkyoyo enterprise at Suame Spare parts dealership area Kumasi engaged survey. The elastic strain stress mathematical models to determine points a loaded spring with aid ANSYS. factors considered analysis SAE design specification, recommended Ghana Highway Authority load limit for vehicles, terrain. Analysis was done standard variable curvature springs. mode found be fatigue loading. causes determined beyond 43 tons per wheel limit, bad roads, reckless driving. It also observed that loading edges bend outwardly from top, making more prone failure. Results further showed recorded energy 2.5 times higher than standards spring.
