ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

      混凝土成型用标准振动台系用于按GB/T50081-2002、GBJ82-1985中成型混凝土试件时的专用设备。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

二、技术要求ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

1、应有铭牌，其中包括制造厂、型号、规格出厂编号与日期。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

2、外表面应平整光洁，振动平稳，声音正常，台面应水平。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

3、电气部件绝缘性能应良好。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

4、基座与基础用地脚螺栓固定。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

5、振动台面尺寸：1000×1000±5mm。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

6、振动频率：50±3HZ。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

7、空载时的有效振幅为0.5±0.1mm。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

三、校验用标准器具ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

8、二级测振仪；ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

9、2m长钢卷尺，分度值1mm。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

四、校验方法ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

（一）外观与工作状态校验ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

10、用感官和启动试验检查，要符合1、2、3、4条规定。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

（二）技术参数校验方法：ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

11、用钢卷尺测量振动台面的尺寸。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

12、用测振仪测振动台面的频率与有效振幅时，应待振动台振动平稳后测，测振点布置在振动台的四周边，共4点（如图一所示）如不能同时测四个点时，至少要同时测2个点。先测1、2点，后测3、4点。所测4个点均应符合第6、7条的要求。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

13、振动频率可根据电机转速测定，也可以采用测振仪测定。 ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

五、校验结果评定ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ

14、新振动台必须全部符合技术要求。ß"]½Åî –bbs.3c3t.comž˜ÃÁ3I aäÔ
