10.试验过程中激振器振动偏离,我该怎么办?

If the shaker is vibrating out of place, misalignment of the stinger and armature will likely be introduced into the system. As discussed previously, proper alignment is critical to good quality measurements as well as to prevent damage to the shaker itself. Therefore, it is necessary to attach the shaker firmly to a base if exciting at levels that result in the shaker walking about during testing. In most cases hot glue provides a temporary bond of the shaker to the floor, solving this issue. Please reference the previous discussion on proper floor mounting techniques if this occurs.

如果激振器振动偏离,系统中有可能引入推力杆和动圈的不对中。如前面所讨论的,对良好品质的测量结果以及防止损坏激振器本身,正确的对中非常关键。因此,如果激励按照某种大小的力幅,最终导致了激振器在试验过程中“走动”,则有必要牢固地连接激振器到一个基座上。很多情况下,热熔胶提供激振器到地面的临时固定,可以解决这个问题。如果发生这种情况,请参考前面关于正确的地面安装技术的讨论。
