High impact frequency - Wire rope sufficient?

[kobuss]

Good morning guys/girls, hope all of you are well.
I am looking for a solution regarding a design I am busy working on. I have a situation where I have to limit the travel between two plates (vertically), but these plates also move slightly in the horizontal plane to. So the “limiting” part should be able to flex as these plates move whilst in operation. The plates will also be subjected to high impact frequencies (and they will carry load).
I started looking online for some solutions. Wire ropes have the perfect flexibility and are very compact (size wise) but to my knowledge they do not handle impact loadings very well (I am not a wire rope expert).
So if anybody out there has any suggestions please let me know. Thanks in advance for the info.

I suggest you contact an application engineer from one of the manufacturers. Without your specific environmental conditions and doing analysis, how could anyone accurately answer your question? Nonetheless, it can be said that wire isolators are routinely used for MIL-S-901D shock, which for naval applications is the most severe shock condition.

Agreed, and failing that, chains.

Coil springs?

You gotta give us a clue what you are talking about and trying to do, we just can’t see it from here. A sketch with some loads, dimensions, good descriptive notes, might go a long way, because your word picture kinda falls short. Let the horiz. plates move laterally in some slide grooves, y-dist. apart, in the main structure. Wire rope will take shock loading just fine, within limits. The connections to the plates will be the tough part. And, when the plates do move laterally the wire rope will tend to draw them together by a small amount, as the angle changes. There are also some half-ball and socket bearings, which a threaded rod fits through. The rod acts as a hanger, and is bolted above and below two opposite bearings, 4 rods thus for plate support. This could be as rough as a half-spherical washer riding on the plates.

I would challenge that assertion of wire ropes not performing well in high impact load applications. Oilfield wireline applications such as pulling tools or logging equipment typically jar downhole equipment. You can obtain some incredibly high tensile loads as a result of this. There is some information in the Machinist Handbook on wire ropes, but a reputable vendor for that product could guide you more.
