Arı Algoritması Kullanılarak Önden Dümenlemeli Bir Aracın Dümenleme Mekanizmasının Optimizasyonu

In this study, the steering linkage of a front-wheel-steering vehicle was optimized using the Bee Algorithm. Here, a four-bar linkage is used as the steering linkage. Steering angles were calculated from the kinematic analysis of the four-bar linkage. Generally, steering linkages of vehicles are designed using Ackerman geometry. Ackerman geometry is the geometric arrangement of the steering linkage designed to solve the problem of wheels inside and outside of a turn that need to follow the circumferences of different radii. The purpose of Ackerman geometry is to prevent the tires from slipping sideways and causing additional lateral loads when following the path around a curve during a turn. The geometric solution to this is that the axles of all wheels are arranged as radii of circles with a common center point. However, it is not always guaranteed that the ideal rule, known as the Ackerman rule, will be met during vehicle rotation. Therefore, the dimensional synthesis has been done through optimization aiming to determine the steering linkage dimensions that both steering wheels must obey the Ackerman rule as much as possible while the vehicle is turning. In this study, the Bee Algorithm was used to minimize the error between the steering angles obtained by the Ackerman rule and the four-bar linkage kinematic analysis. The results obtained as a result of the optimization reduced the Ackerman error and showed that the dimensions of the steering linkage could be improved and presented in graphics.
