COMPUTATIONAL DYNAMIC ANALYSIS OF A FUGAL FLOOR STRUCTURE

SUCROGEN VICTORIA MILL is at the mid-point of a high-grade fugal replacement strategy. Installation of a second Titan 1900 fugal was completed in the 2011 maintenance season. Installing this machine required the fabrication of a new section of elevated, structural flooring. During commissioning trials and into the 2011 crush, significant levels of vibration were apparent in the new floor structure. An in-house computational dynamics analysis of the structure was completed to determine the critical mode shapes and associated natural frequencies. This work was undertaken by a Sucrogen graduate mechanical engineer under the supervision of Sucrogen Herbert district Reliability Engineers. The computational modelling and design revision work is complete and subsequent structural modifications will be in place for the 2012 crush. This paper reviews this body of work and presents engineering recommendations to assist with the design of dynamically loaded, elevated steel platforms.
