Lateral load transfer due to lateral acceleration: The cad model reference was taken for finding the position of C.G in side view, a = 990 mm = 3.25 ft and b = 533.4 mm = 1.75 ft. The component of lateral acceleration along the axis of the car: α = 5, A γ = A α c o s α - s i n α = 0.6369 c o s 5 ° - s i n 5 °, A γ =–0.5498 g’s (negative sign indicates deceleration), Note: A γ = A α (if road is level). Longitudinal weight transfer is much smaller than lateral weight transfer so we lateral weight transfer. Ī α = - 0.6369 g ’ s negative sign indicates deceleration. We have figured out an efficient method of approach in designing a suspension system for a vehicle after undergoing an elaborate research work on vehicle dynamics and various methods to design a suspension system of a four wheeled vehicle. In Terms of manufacturing coilover shock absorbers, the calculation of coil diameters ratio is also performed. The design and calculations carried out is based on a prototype vehicle of mass 350 kg. Here in this design a perfect camber gain is achieved providing a balance between braking grip and cornering grip. This ultimately provides good handling for the vehicle. This is due to negative camber gain they attain, thereby also increasing the traction in corners. Double arm independent suspension systems are widely preferred as they have high ride stability and reliability. The relative movement between the wheel and the Roll cage is obtained by this suspension system. The independent double arm Suspension system consists of Control arms, springs, Dampers and linkage mechanisms that connect the wheel and the Roll cage of a vehicle. Dixon elaborately discusses all the parameters related to a suspension system of a vehicle which provides a complete understanding of the concepts and our manuscript is scripted in such a way that only the exact required parameters are described and used for the calculation. Several iterations have been in order to attain perfection in riding conditions in corners considering lateral load transfers.
Milliken, The design of suspension system for high performance cars involves assumption of parameters such as Roll rate and it involves verifying them at end.
