Designing the suspension system for a formula race car
Journal Title: Modern Innovations, Systems and Technologies - Year 2024, Vol 4, Issue 4
Abstract
The article examines the advantages and disadvantages of various suspension systems. For a Formula Student race car, the double-wishbone suspension is identified as the optimal choice, offering precise control over wheel positioning relative to the road surface. The study outlines the regulatory constraints defined by the Formula Student rules, which must be adhered to for the vehicle to pass technical inspection. Key criteria for selecting the car's wheelbase dimensions are discussed, demonstrating how these choices simplify the vehicle's design while preserving its dynamic performance and maneuverability. The analysis considers the pros and cons of different track width configurations for the race car. The selection process for wheel rim sizes is also explored, with Hoosier 20×7,5-13 tires and Keizer magnesium three-piece rims identified as the ideal combination. The required steering angles to minimize traction losses and enhance cornering precision are determined. The study further delves into the selection of the Ackermann coefficient, emphasizing its role in defining the differentiation of steering angles. Additionally, the deformation of tires under varying pressures and loads both vertical and horizontal is analyzed, with lateral deformation parameters outlined. Finally, the methodology for determining static camber angles is presented, offering insights into optimizing the car's handling and performance.
