Kinematic Analysis and Design Optimization of Rear Suspension of an ATV
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
The objective of this work is to design and analyse the rear suspension of an All Terrain Vehicle. Suspension kinematics are designed for a mini BAJA ATV used in racing using multi body dynamics approach in LOTUS SHARK software. Modifications are done on the current geometry which is a semi trailing arm suspension and rear links are added to increase the adjustability as well reduce the variation of camber, toe, half track width and roll center height. By altering the design the drive shaft articulation limits are achieved which protects the universal joints from damage. By minimizing the variation in toe and camber angle the straight ahead tendency of the car increases also reducing the tire wear on different terrains during the race. The reduction in the variation of half track width and roll center height increases the stability of the vehicle during sharp maneuvers and uneven terrain thus increasing the stability of vehicle.
