The paper describes a method of optimising the motion characteristics of a double wishbone front suspension system, by using the genetic algorithm. The analysis considered only the kinematics of the system. The mechanism is made of two closed loops, the first loop, the main double wishbone mechanism analyses and feeds the results into the second loop describing the steering mechanism. The analysis is carried out in the time domain. As the two loops are linked together overall motion influenced by the kinematics of these loops and the vertical oscillation of the suspension system would result in oscillation of wheel angle. An objective function is designed to represent this. A genetic algorithm is used to vary the 20 design parameters of the suspension-steering mechanism in order to minimise the amplitude of wheel steer oscillation due to vertical suspension oscillation. Although the study is not carried out on any 'real' suspension system, the software could be used as a general design tool.
