基于能量法的路面不平整度评价

摘要

The disadvantages of IRI and PSD pavement regularity degree evaluation index were analyzed, the quarter vehicle model was built and IRI calculation formula was deduced, the relationship between IRI and PSD was obtained according to random vibration theory. The re-search also pointed out that the future pavement irregularity research direction should be based on PSD, three factors of humang, vehicle and road were comprehensive considered, therefore realized harmonious of human, vehicle and road.%分析了IRI和PSD两种路面平整度评价指标的弊端,建立四分之一车辆模型,推导了IRI的计算公式,并根据随机振动理论得出了IRI和PSD二者之间的关系,研究还指出,以后的路面不平整度研究的方向应该是在PSD的基础上,综合考虑人-车-路三方面的因素,从而实现人-车-路的和谐.
