Kinematics and Compliance Analysis of a 3.5 tonnes Load Capacity Independent Front Suspension for LCV 2019-01-0935
This paper deals with the development of a 3.5 ton carrying double wishbone front suspension for a low floor LCV. It is a novelty in this class of vehicles. It has a trackwidth of 1810 mm and it has a recirculating ball steering system. The steering mechanism has been arranged so that the steering angle could reach to 48° that is a very effective angle in that vehicle range. This results as a lower turning radius which indicates a better handling for the vehicle.
The steering and the front suspension system here has been optimised in terms of comfort and handling by using DOE based on sequential programming technique (design of experiments). In order to achieve better suspension and steering system geometry, this technique has been applied. The results have been compared with the benchmark vehicle.
