【摘要】 路面功率谱作为对车辆振动评价的修正参数,是将路面不平度激励信号经过数据处理运算而得到,是研究路面行驶质量、汽车振动响应、汽车—路面动力学的良好指标,怛基于路面功率谱密度的分级标准已经无法满足现代高等级路面客观真实的划分要求,因此对功率谱分级方法进行了改进,提出功率谱面积分级法。更多还原

【Abstract】 Surface roughness encouraged signal has been changed into road power spectrum by data Processor,road power spectrum,as amended evaluation of vibration parameters,is a good indicator to examine the quality of the road,vehicle vibration,automobiles dynamics,but the ISO Road grading standard based on the power spectral density has been unable to meet the objective and truth requirements of Modern high-grade road Therefore,the power spectral area classification method has been proposed in order to improve the ISO Road grading standard更多还原
