Probably not. Not enough information is offered to make formal analysis.

A client came to CDI with a 300 m long downhill and ask the same question. We did try to convince the client no difficulty was envisioned or the need for such analysis. He insisted it be done. Low & behold, we found a flaw in the wound rotor control logic that would have caused a large force disturbance. It was corrected and commissioning went smoothly. ■

It is more than length, power, grade or slope or sequencing of multiple conveyors and their many geometries.

What is a good starting time, starting tension and control of belt slip, vertical and horizontal tensions, belt safety factor and designing to the limits of good engineering practices. Some people cannot accept designs with idler spacing larger than 1.5 m, cannot accept belt safety factors with limits lower than 7:1. What about brakes and brake circuit failures, speed sensor failures, how many "what if" scenarios should we consider. What about ambient temperature, worn belt criteria, tracking errors, pulley locations and influences especially with material build-up.

I could go on. The points is, there is more than one problem and one answer. Much of the need depends on safety, economy, and the need for getting the engineering correct.

Most standards do not cover the true design conditions today for all belt configurations. What is safe for one concept may be quite bad for another. What components are allowed (rubber lagging, ceramic lagging, gravity or fixed take-up, head or tail drive, .....)

Thus, the question does not deserve a simple answer, since there are too many points to the question. ■

Does this conveyor require dynamic analysis?

Most assuredly, the commercial conveyor must be designed to be 'Fit for Purpose' to match the known requirements it must achieve. It must also be as cost effective over the full lifetime Total Cost Operation at the end of the project. ■
