Every year, the Ngadirejo sugar factory encounters the same issue: The sprocket shaft of the eastern C2 rake conveyor at the boiler station fails. This conveyor is used to transfer bagasse from the mill to the kettle. As a result, when one of these components fails, the manufacturing process will be delayed. Static analysis was performed on a failing shaft in prior research, but the life cycle of the shaft was still relatively long. In this research, by employing HQ705 shaft materials, the modal and random vibration on the sprocket shaft was analyzed to determine the cause of this failure further. The analysis was carried out by using Ansys to implement the finite element method. This model used 8523 nodes and 4118 elements in the mesh. For modal analysis, as the number of orders increased, so did the frequency. The fourth and fifth-order vibrations included torsional vibration, with the most complex form, among others, with frequencies of 3061.6 and 3283.1 Hz. Maximum equivalent stress and maximum shear stress occurred at the exact location for static and random vibration analysis. The analysis is relevant to the actual failure that happened in reality. HIGHLIGHTS One of the common problem in the sugar company rake conveyor is failure in the sprocket shaft of the eastern C2 rake conveyor at the boiler station Modal and vibration analysis conducted in order to find the dynamic behaviour of the sprocket shaft rake conveyor Maximum equivalent stress and maximum shear stress occur on the same location for static, modal and random vibration analysis. Those analysis is relevant with the real failure that has been occur in the reality GRAPHICAL ABSTRACT

“…Software, based on the Finite Element Method is used widely for optimization of the process parameters, eliminating the flaws during the material flowing, determination and minimizing the stresses in the tool, etc. Material's behavior during the forming process can be completely predicted by application of the corresponding 16th International Conference on Tribology -SERBIATRIB '19 software in the stress-strain analysis [2][3][4]. Analysis and simulation of the real processes can be done on cold and hot, by correction of tolerances between the die and the drawing tool, what directly influences the thin sheet thickness during the forming [5].…”

In this research, results of experimental investigations and physical model were used as the input variables for numerical analysis of the ironing strip drawing process by application of lubricants. The numerical simulation was realized in the specialized applicative software Simufact.forming. By applying the software for the 3D modeling, a model of the tool element assembly was made, which served as the starting basis for numerical simulation by application of the Finite Element Method. Experimental values of the friction coefficient for each type of lubricants and the contact pressures were used for defining the contact conditions. Numerical simulation of the drawing process was done for each type of the contact conditions between the tool's elements and the thin sheet sample. After conducted tests comparison of experimental and numerical results of the drawing forces in different contact conditions was done. Comparison was done with taking into account appearance of galling due to difficult drawing process conditions. By comparation of numerical results to the experimental one it is possible to interpret what types of simplifications were adopted in creating the experimental physical-tribological model.

This paper presents experimental and simulation study to minimize residual stress in cylindrical deep-drawing process. Eight significant process parameters including initial blank thickness, punch and die shoulder radii, blank-holder force, punch velocity, and coefficients of friction between die-blank, holder-blank, and punch-blank are considered. According to number of parameters, the Taguchi's method is employed to perform design of experiments. The die is designed and manufactured, and the experiments are carried out using AISI 1006 carbon steel sheet. Hole-drilling method based on ASTM E 837-99 standard is applied to measure the residual stresses in drawn cups. Moreover, the deep-drawing process is simulated wholly using ABAQUS/explicit software and the accuracy of finite-element model is verified using experimental results. Finally, the analysis of variance method is applied to define the most important parameters and obtain an optimum level to minimize the residual stress in cylindrical deep-drawing process.
