Optimal synthesis of steering mechanism using double loop four bar mechanism

Abstract

ABSTRACT The main focus of this research article is on the steering mechanism of the vehicle. To get better steering while taking turns, the fixed angular position of front wheels required for each turning radius of the vehicle. Steering mechanism required to obtain an angular relation between inner and outer front wheel of vehicle while taking turns. The function generation task considered fair to co-ordinate angular relation between front wheels for steering mechanism of the vehicle. To achieve a best approximate solution for the function generation task of the steering mechanism, double loop of four bar mechanism is considered. Double loop of the four bar mechanism configuration can tune error in two stages. The first loop of configuration will generate approximate function to correct steering and the second loop will tune function for better accuracy. Mathematical modelling considered for both loops is based on Fruedenstein’s equation. Due to double loop configuration, number of design parameters is required to find out. And the angular relation between left and right front wheel is highly nonlinear, so genetic optimisation technique is used.
