Suspension system of FSC racing car

Abstract

The invention discloses a suspension system of an FSC racing car. The suspension system of the FSC racing car comprises a front suspension mechanism and a rear suspension mechanism, and the front suspension mechanism and the rear suspension mechanism are connected. Stand columns and hubs of the front suspension mechanism and the rear suspension mechanism are made of aluminum, so that the unsprung mass is reduced, and the response speed of the suspension system is increased; reversing of the front suspension mechanism and reversing the rear suspension mechanism is achieved through pull rod structures correspondingly, so that arrangement of shock absorbers is facilitated, the gravity center is lowered, and the unsprung mass is reduced; U-shaped transverse stabilizer bars are used for compensating the rolling angle stiffness of the racing car and controlling the posture of the racing car when the racing car passes through a curve; analysis software Adams is used for optimizing the suspension geometry, so that the effect that the performance of tyres is brought into play to the maximum extent is guaranteed; and part structures are reasonably optimized through software, so that the lightweight purpose is achieved. According to the suspension system of the FSC racing car, machining cost is reduced; and meanwhile, optimized design of the suspension system is achieved in limited time, and four-wheel positioning parameters and the suspension stiffness can be adjusted.

Description

technical field [0001] The invention relates to the technical field of FSC racing cars, and more specifically relates to a suspension system for FSC racing cars. Background technique [0002] FSAE (Formula SAE) was first established by the International Society of Automotive Engineers in 1978. After more than 30 years of development, it has become a grand event for young engineers participating in teams from hundreds of colleges and universities in 15 countries around the world. Therefore, FSAE also Known as the "Academic F1 Formula Racing". The competition rules are more open than the professional formula, and each team is required to design, process and manufacture a racing car that complies with the rules and has good power performance and economic performance within 8 to 12 months. The competition provides a platform for team members to demonstrate their creativity, learning ability and hands-on ability, which greatly exercises the engineering quality of college student...
