网络服务器用Hard Drive的一个振动实验要求实例
这里发一个Silicon Valley某著名服务器供应商对其使用硬盘的要求之一,不知道国内的硬盘厂家是否可以达到这个要求。下面只是Operating vibration部分,要求在整个约一小时10分钟的振动中数据读、写正常。要求在X,Y,Z三个方向别做,总共3个半小时。Profile Parameters

Auto-Save Signals 这个扫频图还够复杂的,贴出来欣赏。 是不是写错了,5Hz,11个g,能实现吗?
回复 3楼 的帖子
您看错了,是0.9g,11.0606是速度in/sec 还真够复杂的,还好位移不大,带减振托吗,Reply to fyga
This is a real sample recently. It is requested to shaker. The response signal on hard drive normaly shoud be larger than this value on resonans point. 这好像是国军标GJB150上的路振试验
