摘要
在职业卫生领域中,振动加速度有效值是最常用的测量值,振动加速度级的运用方便了运算和表述。给出频率计权和时间加权的计算公式和方法、加速度与加速度级间的换算。测量中强调了传感器定位和紧固方法会影响测量结果。
In the field of occupational health the virtual value of the vibration acceleration is in common use. It is convenient for expression and operation to use the vibration acceleration level. The contribution gives the computational method and formulae of the frequency weighting and time weighting, the conversion method between acceleration and acceleration level. The sensor orientation and the manner of fastening can affect the measure result. The keynotes of before-mentioned methods are emphasized.
