Anti-vibration fixings for signage in metro station

Anti-vibration fixings for signage in metro station

Anti-vibration fixings for signage in metro station

We have a prospective job where the client asked us to revise our quote considering anti-vibration to all our signage.
our signage is mostly post mounted, ceiling suspended & wall mounted, inside a metro station.

From a little research in internet, we understood that using anti-vibration mounts / pads will do the job.

My concern is that whether these rubber mounts (not so expensive) are enough to make our signage anti-vibration? or are there some other kind of anti-vibration systems for this application that might hugely effect our price?

Thanks for your inputs.

Is there a specification or does the client just think your structures look like flimsy crap?

RE: Anti-vibration fixings for signage in metro station

Mike just asked a important question: what is the criteria (i.e. allowable displacement, velocity, etc)? It's an important first step on any vibration job. In some cases, I've been fortunate enough to be dealing with a client who knows something about it and can give it to me. (Typically industrial clients.) But more often than not, I have to select it myself. You may have to decide what is acceptable in this case, advise the client of it, and check your signs accordingly.

My favorite detail is to spec 2 nuts, and lock-tight glue for the nuts.

A little black magic that I personally believe in and sometimes spec is to trim the remainder of the bolt shank off past the outside of the nut, and do a sawcut across the end of the bolt and the nut, a few millimeters deep. the messyness of the cut kind of bonds those two new rough surfaces togeteher, (if you'll belive it)

Keep the damn trains out of the metro station. That will reduce the vibration problems significantly. 😊

White Paper - Addressing Tooling and Casting Requirements at the Design Stage
Several of the tooling and casting requirements of a part can be addressed at the design stage. If these requirements are not addressed at the design stage, lot of time is spent in design iteration when the design reaches the die caster. These design issues lead to increase in time and cost of production leading to delay in time to market and reduced profits for the organization. Download Now
