对震动传感器放置方法和放置位置的选择非常重要，它直接影响到SPX-JD-1
平衡系统的平衡精度。震动传感器既可用磁性底座放置，也可作固定放置。
初装时以磁性底座放置为宜，待找到合适位置后再用螺栓作固定。以下寻找
震动传感器的放置位置和放置震动传感器的方法仅供参考：
a、震动传感器的磁性面应平行于“砂轮与工件”的对应磨削面，这时能够最
直接的测得砂轮震动量对磨削所造成的危害，(见下图)。
对内外圆磨和无心磨来说，由于床身沉重．上下震动低于侧向震动，震动传
感器可置于砂轮主轴箱侧面，平行于磨削时砂轮表面，放置位置高于主轴支
承轴承处，并与主轴中心线垂直。面对平面磨和强力步进磨床，以选水平表
面为佳。
b、随着磨床实际情况不同，平衡头可安装于砂轮端面即与主轴螺纹连接处，
也可装于主轴的另一端即与皮带轮端面相连接，但震动传感器应该始终放置
在靠近磨床砂轮的部位。
c、震动传感器应放置在磨床的刚性较好的部位，这样才能精确测得来自主轴
方向的震动。在有些磨床上，砂轮防护罩也有足够的刚性，也可作为放置的
位置。该在线动平衡仪系统采用窄频滤波器，旨在防止主轴旋转时与频率无
关的其它震动被收集和处理。但在马达转速与主轴转速相同时信号失真仍可
发生。因此，仔细反复试验震动传感器放置的部位对减轻干扰源的影响起着
重要的作用。

Vibration sensors placed both magnetic base, can also be used for fixed places.Loaded with a magnetic base is placed at the beginning, to find the right position and then fastened with a bolt.

It is very important to choose the method and the placement of the vibration sensor, which directly affects the balance precision of the SPX-JD-1
system. The vibration sensor can be used as a magnetic base and can be fixed.
initial magnetic base should be placed in, to find a suitable location for fixed by bolts. Look for the following
vibration sensor placement and placed vibration sensor method is only for reference:
a, vibration sensor of magnetic surface should be parallel to that of the grinding wheel and the workpiece "corresponding to grinding surface, then to the
directly measured harm caused by the amount of grinding wheel vibration (see chart).

, the inner and outer circle grinding and the inadvertent grinding,Due to the heavy bed. Shakes up and down below the lateral vibration, the vibration of
sensors can be placed on the side of the grinding wheel spindle box, parallel in the grinding wheel surface, placed higher than the spindle supporting
bearing at and and the spindle center line of the vertical. In the face of the flat grinding and the strength of the grinding machine, the surface of the table is better. Has, is different with the actual situation of the grinder, the balancing head can be installed on the end face of the grinding wheel is with the threaded spindle junction,
can also be installed in the other end of the spindle and the belt pulley side surface of the connecting, but vibration sensor should always placed
in the position close to the grinding wheel.
c, vibration sensor should be placed in a better position of the grinder,So as to accurately measure the vibration from the spindle
direction. In some grinding machines, the wheel shield is also sufficiently rigid, and can be used as a place to place. The online dynamic balance system using the narrowband filter, designed to prevent the spindle rotation frequency does not close the
other vibrations to be collected and processed. But in the motor speed and spindle speed phase signal distortion can occur. Therefore, careful and repeated testing of the site to reduce the impact of the source of the interference on the role of the source of the.
