摘要
运用模糊数学理论 ,本文分析了车辆整车振动模型自由度与计算精度之间的关系。以整车模型的参数作为因素集 ,以驾驶员座椅 1/3倍频带加速度均方根值作为评价集 ,用模糊综合评判确定了整车振动模型的自由度 ,并用试验验证了该方法的正确性。
Based on fuzzy theory,the relationship betwe en the freedom degree of vehicle vibration model and the accuracy of calculation is analyzed in this paper. The freedom degree of vehicle is determined by using fuzzy comprehensive judgment with the parameters of vehicle model and the RMS of driver seat in 1/3 octave frequency band form as factor sets and appraisal sets respectively. Finally,the validity of this method has been verified. This paper provides a reference for the studies of vehicle vibration.
