Mathematical model and performance calculation of a double-wishbone independent suspension

The paper presents a mathematical model based on which performance calculations of a double-wishbone independent suspension are performed. First, the spatial motion of a rigid body was described by coordinate transformation, which provides the theoretical basis for the hard point coordinate calculation of double-wishbone suspension mechanism. After that, a mathematical model of the wheel guide mechanism has been built, and the kinematic performance and hard point reaction load were calculated. The results obtained are useful in the design of new suspension systems.
