Double wishbone independent suspension design
Abstract
The suspension is one of the modern automobile assembly, frame and the axle flexibleconnection up. Its primary function is to pass the role of force and torque between the wheelsand the frame to ease the load of the road to pass the impact of the frame, the attenuation caused by the vibration of the bearing system ensure riding comfort.
Based on thepopulation parameters of the intermediate car, I designed front suspension system.The design uses a double wishbone suspension, and tests four years of college learning outcomes. Specification includes double wishbone suspension introduced, the main parameters determining the damper selection and calculation of the elastic element in the form of selection and calculation guide mechanism design, design calculations stabilizer bar, and use MATLAB to major parts calculation checked.

CATIA modeling of computer-aided design (parts and assembly drawings), computer-aided design CAD drawing (drawing) equivalent to 2.5 A0 drawings, translate foreign data copy editing a manual included in the design.
Key words: double wishbone suspension，guide mechanism，absorber，absorber springs，stabilizer bar

2. Determination of the overall layout of the suspension and the main parameters
2.1. Overall layout of the suspension
The design is based on the overall parameters of a mid-size sedan. In view of the design time, economy and the characteristics of the double wishbone suspension, the front suspension of the modified vehicle still uses the double wishbone suspension, but the related parts and components need to be recalculated and selected. Simulate and check its feasibility.
