Design analysis of rotary turret of poucher machine

SummaryThis paper present design analysis of rotary turret plate of 5kg capacity for food product packaging machine. The turret plate has been designed considering two different criteria, first one is inertia force approach with only self-weight of turret plate and second is with mass of pouches. A 3-dimenssional CAD model of rotary turret assembly has been prepared in using solid modelling packages CRE-O. The finite element analysis (FEA) of turret plate has been carried out using analysis software ANSYS 15.0. Consideration of inertia force is one of the criteria to analyze the performance and behaviour of component in working condition. The rotational velocity is applied at the central axis of turret and friction less support is applied on inner surface, where shaft is being attached. Also, pressure is applied on the same surface to incorporate the shrink fit condition of the assembly of turret plate with shaft. The boundary conditions as fixed support have been considered at the different sixteen faces, where bolts have been attached. The obtained simulation results for induced stress, deformation and strain depict that the modified design of rotary turret plate is well within the allowable stress limits of considered material. And, further optimization can be performed for topological and strength based more efficient design of turret plate

Continuum Solid Modeling based FEM Simulation Approach for Single Walled Boron Nitride Nanotube based Biosensing

AbstractThe present paper investigates the vibrational characteristic of fixed free single walled boron nitride nanotube with attached bacterium or virus on free end to explore their suitability as bacterium or virus detector device or biosensor. The continuum solid modeling based finite element method approach has been used to analyze the various modes and resonant frequency shift caused by bacterium or virus on beam tip. The obtained simulation results have been compared with analytical results based on fixed free beam bending model. To be more precise in present analysis, the vibrational characteristic of four types of single walled boron nitride nanotubes of different lengths of same diameter have been considered. The different types of bacterium or virus at the tip of the fixed free single walled boron nitride nanotubes have been analyzed for their resonant frequency variation based analysis. The obtained simulation results have been found in sensible agreement with the analytical results. The obtained simulation results suggest that detection of the bacterium or virus having mass of 2.90 x 10-23 kg can be effectively performed
