- Abstract
To improve the design quality of steering system of the large wheeled harvester in China, an optimization method based on multidisciplinary design optimization (MDO) is proposed. According to the requirement of how to design and optimize the large wheeled harvester, optimal variables consisting of steering wheel toe-in angle, kingpin caster angle, kingpin inclination angle, steering wheel camber angle, length of steering trapezoid arm, angle between steering trapezoid and forward direction, distance from the intersection point between vertical axis and guide wheel axis to the intersection point between vertical axis and guide wheel split, driving wheel cornering stiffness coefficient and driven wheel cornering stiffness coefficient are chosen. Take error between the inside and outside wheel angles, dynamic response error between driver input and vehicle response, rolling resistance coefficient as optimal objective, a MDO model is established based on the constraints of steering stability, returnability character, steering portability and design specifications. The hierarchical level two systems integrated algorithm is taken as the multidisciplinary solution strategy after the planning and decomposition by the non-hierarchical structure. Finally, he MDO method for steering system of large wheeled harvester is validated by a certain design example.
