基于突变级数法的振动压路机选型方法

Selection of Vibratory Rollers Based on Catastrophe Progression Method

基于突变理论,提出了振动压路机选型的突变级数法。首先对评价目标进行多层次分解及数据的归一化处理;然后构建突变模糊隶属函数,并计算突变模糊隶属函数值;最后计算总突变级数值,据此对振动压路机进行优选。研究表明,该方法可靠性高、客观性强,为工程实践提供了一条新思路。

Based on catastrophe theory, catastrophe progression method of selecting vibratory roller was pre-sented. The multi-level objects were analyzed and standard quantization of assessment indices was performed. The catastrophic fuzzy affiliated function was constructed and the values were calculated, and the ultimate catas-trophe progression values were calculated, which can be used to select vibratory rollers. The study shows that cat-astrophe progression method has practical value in the selection of vibratory rollers.
