Abstract：Wheeled articulated construction vehicles are widely used in agriculture,construction,mining and other complex road conditions due to their good mobility and pass ability.As one of the most important components of articulated vehicle,the steering system has direct influence on steering stability and portability.In order to improve the steering performance of articulated steering vehicle,an articulated steering vehicle model was established in ADAMS,and the accuracy of the model was verified by vehicle ride comfort experiments.Secondly,the coordinate of the connecting point of the steering cylinder and the front and rear body as well as the articulated point of the vehicle are the design variables,the expansion ratio of the cylinder and the articulated Angle are the constraint conditions,and the interference of the steering cylinder is considered at the same time.Finally,through ADAMS and isight co-simulation optimization,the multi-island genetic algorithm was used to optimize the design variables and obtain the optimization solution set.The optimization results showed that under the same cylinder pressure condition,the maximum articulated angle,maximum stroke difference,maximum arm difference and other target parameters were greatly improved.
