频率计权 meaning in Chinese
frequency weighting
Examples
- In light of the analysis data results of these experiments , vibration comfort evaluation of human in recumbent position should be done in accordance to the vibration of recumbent passenger ' s head and buttock , referring to the international standard iso2631 / 1 - 1997 ( e ) , as well as on the base of correlate studies of whole - body vibration in recumbent position . accelerations of the head and buttock measured have been weighted twice to get at the frequency - weighted acceleration at the buttock and head , the weighted acceleration then is used to evaluate the comfort of human vibration in recumbent position
依据试验数据分析结果，卧铺客车卧姿乘客振动舒适性的评价应依据头部和臀部振动进行，参照iso2631 - 1 ： 1997国际标准，并在相关卧姿振动的评价研究基础上，对测得的头、臀部位加速度值进行计权处理，得到臀?头部位频率计权加速度来评价卧姿乘客全身振动的舒适性。 - The results showed that , the comfort rates of common sleeper bus on three and four class roads are fourth and fifth grade at average . the weighted accelerations on the back part of the advanced sleeper bus on highway is between 0 . 50 ~ 0 . 68m / s2 , its comfort is 3 class degree ; the weighted vibration acceleration of train ' s in the beneath soft berth on plain main line is 0 . 5 ~ 0 . 6m / s2 , and the comfort degree is 3 class ; the upward berth vibration comfort is 2 class
数据分析表明，普通公路卧铺客车在三、四级公路上的臀一头频率计权加速度值在0 . 50 - 1 . 30in / sz之间，舒适等级主要为4 、 5级;在高速公路上高档公路卧铺客车的后部下铺的臀一头频率计权加速度值在0万。
