Side bar space is accurately adjusted by numeric control panel 侧板间距调整，用电控数字显示，尺寸精确。
2.
The natural vibration spectrum curve is measured and the critical velocity to induce trashrack bar galloping is calculated . the effect of bar spacing on the bar strain and the characteristics of the exciting force are discussed . by fatigue analysis it is obtained that the service life of weld at the fixed end of the bar is about 13 分析了发电工况和抽水工况时的振源特性，讨论了栅条净距对栅条应变的影响，按钢结构设计规范对栅条进行了疲劳计算， 1 ~ #测点处可视为不会发生疲劳破坏， 2 ~ #测点焊接处的疲劳寿命约为13 . 6年。
