Abstract
The double wishbone suspension is used as the rear suspension of the Haval H6 SUV. Since the double wishbone independent suspension has a different construction from the conventional suspension, it can improve the handling stability and comfort of the car, so it is widely used in the suspension layout of modern cars, and it is also a kind of advanced suspension form.
In this graduation design project, the basic parameters and positioning parameters of the double wishbone independent suspension will be designed first, and then the parameters of the various components of the steering mechanism of the suspension are analyzed and calculated according to the design experience and the design formula. Also according to the basic parameters of the suspension, these design parameters are checked and modified. After completing the parametric design of all parts, Catia will be used to model three-dimensional modeling of the suspension and get the overall assemble of the system. Finally, by using the simulink module of Matlab, I build a two-degree-of-freedom vibration system model of the car, then input the basic parameters of the designed suspension to verify the reliability and comfort of the suspension.
