Structural Analysis Of Sugar Dryer Assembly

#

Our customer is design, engineering, and manufacturing company of critically customized industrial equipment. One of their leading products is sugar dryer that works on the principle of flow of hot air over sugar particles. Sugar particles are oscillated as they move on a vibrating perforated plate. Frequent failures were observed, mainly, sharing of bolts that hold leaf spring and flattening of bracket.The client resorted to finite element analysis to eliminate failures in the dryer.

Finite element analysis was carried out in ANSYS for the leaf spring, bottom plate and flange. Higher order 3D elements SOLID87 and SOLID186 were utilized. Load pertaining to eccentric displacement was applied to leaf spring. Similarly, self-weight and centrifugal load was applied to base plate. It was found that spring leaf is failing as stresses were higher than the endurance limit. Analytical calculations were alsodone to compare against FE results

Customer was given recommendation of increasing the width of leaf spring and introducing a fillet in bracket to reduce stress.Simulations toconfirm m the benefit of these modifications were also delivered. Thestudy allowed the cus tomertoidentifytheproblematic areas in the des ign. These were incorporated to obtain robust operation of sugardryer.
