摘要
利用实验室自制的振动台作为激振设备,依据机械行业标准JB/T6697-93规定,对改进后的撒粮报警器与故障报警器进行抗振性能测试,即对两种报警器进行上下、前后、左右三个方向的定频振动试验,利用YE7600动态数据采集分析系统对振动信号进行采集分析,对两种报警器的抗振性能做出评价。实验表明撒粮报警器与故障报警器的性能良好,符合有关抗振规定。
Self-manufactured vibration table was adopted as a vibration exciter to make a anti-vibration test of the improved grain-loss monitors and fault alarms according to the standard of machinery industry JB/T 6697-1993. Fixed frequency vibration test on annunciators was made in three directions： up and down, back and forth, left and right.The YE7600 dynamic data acquisition and analysis system was used to collect and analysis the vibration signals in order to estimate the anti-vibration performance of the two annunciators. The test shows that the performance of grain-loss monitors and the precaution device is high and up to the relevant stipulations.
