摘　　要：提出了一种基于轮心六分力的麦弗逊悬架动载荷提取方法.采用解析分析方法建立了麦弗逊悬架系统的动力学模型,研究了该动力学模型的求解方法.为了提高求解精度与求解效率,提出了一种BFGS与PSO相结合的数值算法,能准确高效的求解出悬架系统各铰接点在任一时刻的动载荷.在相同工况下,利用本方法获得的悬架铰接点载荷同ADAMS虚拟样机试验获得的结果进行了对比,验证了模型和求解方法的有效性.并将该方法用于某型SUV麦弗逊前悬的动载荷预测当中,取得了很好的效果.A dynamic load extraction method of Mcpherson suspension based on 6-axis wheel load was proposed.The dynamic model of Mcpherson suspension system was established with the analytical analysis method.And the solution method of the dynamic model was also studied.In order to improve the solving accuracy and solution efficiency,a numerical algorithm based on BFGS and PSO was proposed,which could solve the dynamic loads at any moment of every hinge of a suspension system accurately and efficiently.Under the same working condition,the results of ADAMS virtual prototype test were compared with those obtained with the method presented in this paper,and the validity of the model and solution method was verified.The method was applied to predict the Macpherson front suspension load of a certain type of SUV,and good results had been achieved.
