目前在手传振动工具(件)的研究中,对振动工具的物理参数进行测试时,由于工程上的原因,要建立直角坐标系,分别测出其x、y、z、三轴向的加速度(或计权加速度)。在进行卫生学评价时,根据现行的国际标准,仅取三轴向加速度中数值最大的一个作为评价依据。现对这种评价方法的合理程度进行一点分析和讨论。 我们知道,在测振时,安装固定了拾振器后,振动工具的x、y、z三轴向也就确定了,而且要跟手臂的x、y、z三轴向一致。手臂三 At present, in the research of manual transmission vibration tools (pieces), when the physical parameters of vibration tools are tested, due to engineering reasons, rectangular coordinate systems should be established and their x, y, z, triaxial acceleration (Or weighted acceleration). In the evaluation of hygiene, according to the current international standards, only take the value of the three-axis acceleration maximum one as the basis for evaluation. Now the reasonableness of this evaluation method to a little analysis and discussion. We know that in the vibration measurement, the installation of a fixed vibration picker, vibration tool x, y, z three axis will be determined, but also with the arm x, y, z three axis consistent.
