An investigation into the design of hollow accumulator rolls using finite element analysis
| Title: | An investigation into the design of hollow accumulator rolls using finite element analysis |
| Author: | Viviano, Anthony V. |
| Description: | Accumulator systems consist of a series of rolls arranged either vertically or horizontally which are used in many sheet processing lines for the purpose of storing up strip. Strip is stored so that when supply coils run out new coils can be welded to the ends of old coils without stopping the entire line. Literature on roll design is scarce because companies that have developed present design practices are reluctant to offer this knowledge. Given the fact that many rolls make up some accumulator systems, the cheaper manufacturing costs associated with some designs would be very desirable providing the design is acceptable. Much of the present design theory is based on a static analysis assuming the load from the strip is evenly distributed over the roll and there is negligible loss of load in the strip going from one side of the roll to the other. A previous thesis done on this subject focused on modeling the roll using finite element analysis, FEA, and making these same assumptions. This research focuses on using FEA with nonlinear contact elements located between the strip and roll in order to allow the software to distribute the load from the strip to the roll. From the results of this analysis it will be reasoned whether the present design assumptions concerning load transferal are valid or not and a goal of this investigation is to verify or discount the previous work that was done. |
