Computer aided design and analysis of a double wishbone suspension for heavy commercial vehicles

Independent suspensions are being used especially at passenger car front wheels for a long time because of their driving dynamics and comfort advantages. However due to high load capacity and ease of production; heavy commercial vehicles mostly use rigid axles for front wheels. In this study, a double wishbone independent suspension has been designed with computer aid for heavy commercial vehicles. Design process of parts are carried out with 3D parametric modelling, making necessary calculations and performing FEA studies with ANSYS Workbench software. Selection calculations for standard parts also done. Important factors such as weight, manufacturability, standard part usage, ease of assembly and maintenance, cost also have been taken into consideration at design phase.
